The footage doesn't exist to do the story properly. I am asuming that you are thinking of the 1st drafts of Star Wars that Lucas wrote back in '74 or so, with the Jedi Bendu and all that.
However...
It might be possible to recreate the story or the early drafts through a narrative presentation, kind of like Move Along's The Story of Star Wars project. You could re-write the early scripts into a narrative and speak over edited together existing footage, using the original audio where it fits. This might be one approach.
