A few years back, I used a Jedi character I had created for my friends' RPG campaign to a story using the idea of dual timelines: because of an imbalance created in the timelines due to a "fracture in the Force", he kept switching between two timelines (EU and the Movies) and the two timelines were in danger of collapsing altogether unless he could somehow stop the growing rift.
It was called Star Wars: Dual Forces; I'll have to check my old hard drives to see if I still have the artwork for it.
That sounds cool!
