Thing with Aerith and Tifa is you can make the case for both of them trying to edge Cloud into the SOLDIER persona, Tifa because she likes the idea of Cloud as a hero, and Aerith because she likes Zack and sees him in Cloud. They each sorta want Cloud to be that hero image for their own reasons. Now, I don't think Tifa was trying to shoehorn Cloud into that hero image, anymore than I think Aerith was trying to shoehorn him into being Zack, but there's a basis for both schools of thought. I don't think Tifa was trying to make Cloud the hero she had fantasized about and don't think Aerith was trying to make Cloud into Zack 2.0, but if you think so fine, your claims aren't entirely without merit.
Now, a few things. First, this isn't necessarily a bad thing, because Cloud's growth from a selfish mercenary with false memories to a true hero is his character development. Tifa and Aerith both pushed him to stop being a dick and be more heroic and discover who he really is. Second, who can say with honesty they haven't tried to change they're significant other for the better if it would make them a better person? This isn't a bad thing though, sometimes you need someone else to see the good in you and bring it out. Thirdly, Tifa and Aerith both got over their desires to make Cloud into the man they want and love the guy he really is underneath the complexes and fake memories, so more power to them.
