Really? Who?
The most anybody knows about Lucas' original vision is things he's talked about in a few interviews about how he wanted to take the series microscopic, literally. It was gonna be about how midichlorians were true conciousness, and people were literally just vehicles the midichlorians controlled and moved around in.
Yeah, Lucas definitely wanted to go somewhere that wasn't standard blockbuster fare, but just cuz it's weird wouldn't have made it worth seeing. He couldn't even handle a tragic hero for the prequels, and all he needed for that was to rip off Shakespeare, which some writers have made an entire career out of for centuries now.
