That would be nice, indeed.
But, VVVVVV is closed source. The game is quite simple, though, and maybe the author of the Pandora port, pickle, made the port (the programming part) from scratch? In that case you could try to contact the author and ask for the source (if he is willing to share it). Unfortunately, the link you posted does not have the source code, and the author's home page resolves to some random pr0n page (he probably forgot to renew the URL...).
You could also try to contact the original author of VVVVVV, and ask if they want to make an official port (I believe some indie developers who have made some commercial games, have had interest in the GCW Zero, too, so it is not impossible they'd show some interest, though unlikely). There's already an official Linux port, but I still think that the changes could rise, perhaps, if/when there's a shop for paid GCW Zero software. That way the original author could get some compensation for the porting.
Otherwise, the changes of seeing a port are quite small.
