I'll check out your draft when I have some time, but I think I'm just meshing thoughts together. In my mind it is almost like listening to the audio play "Hunt The Truth" for Halo. It wasn't interactive but it was very immersive. The writing was good and the sound effects not only fit the world of Halo, but sounded like it could be real. This thought meshes with an idea i had for a video series for the text-based "Choice of" Games where I (and possibly others) would play through a game and produce a script and voice over it as seamlessly as possible, completely turning into a narrative audio-book-esque lets play. This would almost be an interactive audio-book.
With the right execution I have no doubt it could work, but it is hard to conceptualize something with little reference to anything one has seen before. That said I am certainly intrigued, even if I don't fully grasp the concept.
