One idea I had is to find the best band for each song in the game (through competition online) where the actual artists of the songs are all alive, kicking, and together. Provided they would be willing to cooperate, train the members of the actual band in the game for a while, and then face them off against the best Rock Band players for the song and see who comes out victorious. Likely the Rock Band players would almost always win, but it would be a fun event to observe regardless.
Another idea is to incorporate motion sensing a little more in depth. Attach some of those motion capture tools that would come with the game (or be purchased separately) to yourself. And the guitars and mics (what the hell, drums and drum sticks too!) would already have the motion capture sensors installed. As you move the peripherals and yourself in real life, the motions are translated into the game via your character and it's your actual movements on the screen. I guess just using something like the PlayStation Eye would be more sensible, but it wouldn't be nearly as cool.
Outlandish enough for you? Post your own barely feasible ideas!
