Speaking of volunteers, whole new scenes could be easily created with the assistance of the 501st Legion and their rebel equivalent. Costuming Stormtroopers and Rebels wouldn't be a problem, probably wouldn't even cost a penny. Locations would naturally be any forest that's available but preferably one of the Redwood National and State Parks. The only difficulty here would be gaining permission to shoot, but this is, again, possible.

Good luck getting the 501st or Rebel Legion involved. If it even smells like it's going to make Lucas mad, they won't even discuss it. You'd have much better luck getting a bunch of random costumers together. You'd basically be asking them to reshoot entire portions of Jedi so you can make a fan edit that has Wookiees instead of Ewoks. They don't usually look to kindly on things like that.

If anybody from the 501st or RL did participate, they'd be risking any kind of reputation they've built up with those organizations and LFL. If something went bad, they'd either be excluded from future events for some time to come or they'd be kicked out entirely.

They may be a bunch of elitists (personal opinion), but they have very good standing with LFL and they aren't going to do anything to jeopardize that.
