Maybe if Jedi starts with the emperor's arrival, there'd still be a star destroyer at the beginning? The whole second death star thing is a pisser. "Spreading it around" like this is cool, and could help. Maybe it wouldn't feel like such a re-hash if the briefing scene is somehow re-cut to grimly emphasize that this time it's an ASSASSINATION. Killing the emperor is the goal instead of another death star graphic, another "knock out the main reactor blah blah" speech...
