I agree with Del and BoB. It didn't bother me hugely about the lack of personality amongst the player characters because it's not all that uncommon (Link from Zelda? The main character in a Pokemon game?), though I certainly think it might make the game better. Having said that, it'd be interesting to see how they'd actually make that work because presumably they'd need to give each character a back story/reason for being part of the Warriors of Light. I think VeloZer0 is right though, if they're going to put that much work in, they might as well make a new game.
