Sites fine I wouldn't change the name, loved the mod demo do you think it is going to be much too complete though seems a hefty task changing to the field models and making the big edits to the story, I would be happy with chibi models and original story with name and reference edits as long I get to play the full campaign with Sephiroth.
I like the UI update one favour though could you use the original Sephiroth avatar mainly for matching in with the rest with of the games avatars I am not a big fan of the digital art versions they just never seem to fit with the game to me.
