I know this thread hasn't been touched in almost a year, but I can't help but wonder if anyone is still working on this.
Even a quick and dirty version of SW with unretouched deleted scenes integrated would be a nice version to watch for those of us who want to see how much the scenes would add or detract to the flow of the story as we know it.
Biggs has a story that needs to be told, because it's only a few minutes on film, but it is part of the backstory of our young hero, and shows us more about who Luke was before his fateful run-in with two robots who sweep him up in a path that Luke is destined to walk. And the losses that Luke must overcome are even more overwhelming, because in addition to losing his aunt, uncle and the recently met, Obi-Wan, he also loses his childhood friend who shared Luke's dreams of leaving their backwater homeworld and becoming adventurers among the stars.
