I"d be interested. I've done a few with a combo of midi and real tracks, and sold a few, although they were not perfect with the proper hooks etc. There is an immense amount of talent here, the business details could and most likely would get a bit sticky.
Here is a sample of a tune with no melody line, this is actulally midi tracks converted to audio, with some effects for mixdown and master.
