What's the real reason you don't add Modern Aesthetic to Viera?
I know it's not the head shape/ears. Yes, they're probably not a straight transition over from the other races from Viera but it can definitely be done. I know it can be done because their is an entire modding community doing it and making it work. You could literally just buy the work they did and implement it.
I think the real reason you won't make them compatible is because you fear with Viera having access to all the Modern Aesthetics you'll see a 20%-30% player base Fantasia over to them and you don't want to see a single race have such a large presence in the game.
Prove me wrong, tell me your side of the story on how Square Enix developers can't do something that a team of 1-3 modders do in their basement.
