id be really interested in seeing a rough cut.
i really enjoyed the clips you posted, and would happily see a "work in progress" version, just for the ideas and composition.
maybe after a rough cut, you could subdivide the film into small sections, ie, bar scene, speeder chase, dialogue scene, and maybe people could have a crack at taking one a nd implementing the ideas after spending more time on it, like some collaborative film.
have you ever considered making this in the format of a tv series? with a "previously on star wars" opening perhaps? the parallel storylines could create sufficient tense ending points.
