Well if you like stale bread then go for it.
Just as practically pointless are projects turning Hero controllers into MIDI axes.

Having tried the World Tour sequencer, playing them under studio conditions aren't
that fantastic. It's only a crippled, clumsy keytar. But the novelty value's through the roof.
It works best with the console preset sounds anyway (which could be easily Melodyned), so I would question why people haven't demanded MIDI in for external control. Which you have on the drum set, channel 10:

And there's the actual MIDI guitar for the PS3, for halfway house.
Mind you, features abound the Hero sequencer, like pitch bend, trick chord sounds, scale selections and note edit. Best thing I could do for myself is make a Kontakt pack and play my real MIDI axe, though I'd miss a fun trick the strum switch and lever together can throw. (And what fun could I have with other licks from the games?)
And to use the drums, you don't even need a software go-between for the MIDI out, unless a realtime channel changer:

Limited use, but there we go. Pleasure enough in the retro room, old consoles as drumboxes.
