Sugestion for awesome homebrew game

now I know this would take really long to mke but we've made guitar hero for PSP and last night I hade a dream that there was sometthing like rockband for PSP where to sing you use the head set and the PSP would have to link together useing AD-HOC and drums you would have to just hit X O [] and /\ and drum what do you guys think I know it would take a long time to make but still it would be kool and you would need a career mode unlike gunnar hero that would be sick and I would help.

That would take a lot of work.
I don't know if anybody would be willing to do it.

yea still it would be cool
