That would have been an interesting ending. Would've hated it as a kid, I'm sure. But, as you age, you mature (ideally) and I think I would have respected that sort of plot move as I got older and even liked it. I like the idea now. May have also pushed Lucas to do episodes 7-9 right away because an event like that would need some sort of follow up in terms of retribution. We may have actually had all nine films by this time had that happened.
