At this point, there are such groups of people:
1. Those who played a game and liked new protagonist;
2. Those who played the game and disliked new protagonist but not only because of looks, but because of his personality too;
3. Those who refuse to play;
4. Those who simply watched playthroughs and were satisfied with that;
5. Those who simply didn't play yet, but are just interested in this game as something that has nothing to do with original IP.
I really don't think that ant of said groups are going to be interested in new skin.
I'd like to point out, that the whole controversy could have been avoided if they named characters differently from their original incarnations. For example, call Dante Caesar and Vergil Julius. Also, change Spardas name to Mandus and make him a younger brother of Mundus (TWIST).
See? Devs are sattisfied, because they can do whatever they want and fans are satisfied too, because Dante wasn't in the game, so he wasn't changed a bit.
P.S. Angry Joe called it.
