I'm going to show you two reasons why ripping models from CC is a bad idea.
As you can tell the models not only are not made for ff7, they are ugly when they are placed on armatures that are not theirs. This does not make the game look "pretty" at all and in fact makes it even more hideous.
You can't force others to think the same as you =/
There are people that prefer chibis, people who prefer tall chars.
Everyone's different.
Edit:
+ there are ways to fill holes and fix animations
