Your theory for why the Reports can't exist post-FFI is indeed compelling, but you mentioned cause-&-effect. In that regard, I would say that the cause of the Reports was the birth of Garland.
Sure, all the parts about the memories of Cid's wife should still be there. There's probably no reason those wouldn't still be made.
I should have been more specific. I was talking about the parts discussed in the final two Cosmos Reports, with the details about the Four Fiends and the prophecy.
Those parts should be gone.

As for the continuity argument, here's my viewpoint: You typically don't take the minimalistic approach when you establish links. Think about CC. It has the Nibelheim scene, Midgar is another location, the abandoned town is mentioned as being close to Icicle Inn, various characters from the Compliation appear, etc.
You could make an argument that all you need to have a canon game is Genesis. He's technically in SOLDIER. All of the locations & other characters can be new, different, & unrelated, since your villain has a tenuous link to the canon. This is technically true, but it doesn't mean all of the other elements that are in CC have a specific purpose beyond being part of the setting. In fact, for some characters, this is quite literal. Aerith is a major character, but she doesn't have much significance beyond hanging out with Zack.
True enough, but on the matter of the prophecy details in the Cosmos Reports, there's nothing they could be providing the setting either. Between the presence of Chaos, Cornelia in the game's ending, and all the other details in the Cosmos Reports and Chaos Reports, it was already clear that we were dealing with FFI's world.
If they're not giving us information about the ending, then they're really not doing anything but just being mentioned to fill up space and pad the reports out to an even 10.

On an unrelated note, here's something I've observed:
-FF1-
Chaos uses magic from the elements of water, fire, earth, & air.
-Dissidia-
Cosmos is thematically linked to water & air.
Chaos is thematically linked to earth & fire.
I'm not sure where I'm going with this, or even if the observation is significant, but I thought I'd throw that out there.
It's significant, I think. I'd noticed the recurring imagery, but it didn't even occur to me before that there's an association with the crystals there.
It actually makes quite a lot of sense. The crystals of FFI's world apparently sustain the planet's order. Similarly, Chaos and Cosmos are described as the pillars of the world.
They're related to the crystals somehow, probably, either part of the world sustaining function or with one being a reflection/representation of the other.
While on that subject, I've gone ahead and translated Chaos and Cosmos's profiles from the Ultimania (pp. 174 and 178, respectively):

-------------------------
CHAOS
Reigning in a far-off dimension, the god of destruction and chaos
A sinister-looking, grotesque god with horns, wings, a tail and four arms, he governs chaos. One of the two gods who are the pillars that sustain the world, his fate to be in conflict with Cosmos -- his opposite -- is all according to the "Great Will." Though it was believed the conflict would last for eternity, this time, he was victorious in his battle with Cosmos, and serious changes begin to visit themselves upon the world, as well as his own mind and body.

In order to maintain his ability to fight, he selected a group of warriors, each from the worlds of various dimensions, to fight against Cosmos and the forces of light under her command.

COSMOS
The goddess of order and harmony, who embraces everything with the light of kindness
One of the two pillars; together with the god of disorder, Chaos, they constitute the world. The beautiful goddess who governs order and harmony, she watches over everything with the warm look of an affectionate mother. Though it seemed her conflict with Chaos would last for eternity, this time, she has lost to Chaos's endless forces. Her remaining power bound in sustaining the world, she bids the warriors she summoned begin their journey to find the crystals.

With the world descending into chaos, she transmits a message to the Warrior of Light and the other warriors who bear the power of light, entrusting them with the light of her wishes, for the sake of the future.

Even if she can't travel with the warriors, she constantly keeps a watchful eye over them, and when the hardships of their journey for the crystals puts them in distress, she materializes nearby to give them advice.

Cosmos wished to sever the endless cycle of battle with Chaos. Without telling them much, she requests the warriors find the crystals; their true purpose is......?
-------------------------
I think the statement that they "constitute the world" (構成: "compose," "constitute," "comprise" and similar words) is significant. It points to much the same idea that we see with the crystals.
Minor addition. It was pointed in another area of the site, ironically in something pretty much completely unrelated to any of the subjects discussed here, in a conversation that I was not in, that the crystals probably are just representations of significant objects.
The point was made about Zidane's crystal, & that there's no way it could have been the original crystal. It's too small & why the Hell would Zidane be walking around with the original crystal, anyway?
Yeah, the crystals seem to take the forms of crystals significant to the worlds the heroes come from.
That may be another indication toward the potential significance of the crystal the Warrior of Light carries, and -- between that and the relationship you've pointed out between the gods and the crystals -- explain why his crystal could affect the Water Crystal.
Certainly, Cosmos's power should still be lingering within the crystal he received during Dissidia, so that may provide the spark to restore the Water Crystal when FFI's Warriors of Light reach it and defeat Kraken.
Something else that just occurred to me that points to Dissidia being a prequel is that the WoL notes that he alone has no memories of where he was prior to the conflict of Dissidia: "Unlike all of you, I have no memory of where I was, or where I must return. I don't even know my own name."
That's the same state we find him in during FFI. The
Circle of Sages -- as well as
Dissidia's Japanese website -- mention that the Warriors of Light didn't have memories of where they came from, so it stands to reason, I think, that he hadn't yet gone through his journey in FFI.

Still not sure whether or not WoL's crystal is the ice crystal, but here's an attempt at making a coherent story out of this:
After shit goes down in Lufenia, Garland is understandably traumatized. This explains his memory loss. The Rift dumps him outside of Cornelia, where he goes through a relatively normal life as a knight. He doesn't know the full extent of his powers, but he knows he's the best knight around. Because of this, he goes mad with power & tries to take over Cornelia. He takes the lute because he's unconsciously aware of its significance.
So far this sounds workable. I've always thought that Garland took the Lute more out of a subconscious allure than because he knew what it did.
NB said:
After being defeated by the Warriors of Light, he ends up in the Rift again. Rather than go straight back to the past, he roams around, whereupon Cid finds him. It's Cid who leads him to the time paradox.
Here, it's less likely. Garland explains when confronted by the Warriors of Light before their final battle that the Four Fiends sent him back in time right after he was defeated:
