You could always make little figurines of toribashians, like they do for other games like Final Fantasy and Kingdom Hearts. Have little statues of certain poses or particular frames in awesome replays.
I am using the Wii to post this and it's my first time using it. It seems very possible to make Toribash for it. It wouldn't be very hard to play because you could move the controller like the mouse and press the buttons which would be like clicking a mouse or using the keyboard.
