I'd say it sounds interesting. Maybe with the potential to be very confusing if it gets away from you but that's not necessarily a bad thing.

Also, I'm very much looking forward to your big bang. I've read you Inception drabbles so far (which is actually what got me interested in seeing the film so kudos to you) and I think my favorites are the Cobb/Fischer stories although I was fascinated by the precept behind "Defense Mechanisms". Did you have any plans to include those elements in your BB fic? Not that I won't read it anyway, but I'm curious ^.^
