What other Rock Bands could be made?

I personally want to see a Pink Floyd Rock Band out there, play keyboards or something, come on, that would be awesome and you all know it, What do you want to personally see out of Rock band? As in promoting a band or anything.

Rock Band Speed METAL!

I dont play Rock Band, but I think a Floyd one might just get me to play...

Actually, you know what they really need? A rock band Bluegrass special edition, with banjo, mandolin, violin, stand-up bass, washboard, etc. I would definitely play that.
