Sounds like a lot of fun. I’ve long thought that Lovecraft’s “Call of Cthulhu” would be perfect for this kind of treatment - after all, the story is just an assembly of letters and documents with descriptions of sculptures, photographs, etc. - you just replace the descriptions with real sculptures, photographs, letters, etc. It would also be fun to do this with a completely new narrative, and maybe throw some video and/or audio in there, as well.
