Donkey Kong would have been a cool player character but the game ultimately doesn't work since he has different geometry than Mario and Luigi (and what part of him is considered a hit for stopmping on an enemy for example). Wario and Waluigi are evil, they don't belong as heros even if you explained it somehow, I wouldn't want to be them. I think it would have been awesome with a slightly different story somehow and having Peach and Daisy as player characters so girls can play as them.
