Personally, I think the opening shot of every episode should include a ship flying overhead, preferably with a planet below. In my mind, I think it's just as important as the opening crawl. This is one of the great missed opportunities of the saga. There are ways to accomplish this without each one seeming like a re-hash too. For example, ADigitalMan's opening of Episode II is brilliant: we pan down on Coruscant and then the queen's ships spin in.

Episode I should have opened with a pan down on Naboo with tradefed ships in orbit, then the starcruiser flies overhead.

A great alternate opening for the original ESB would have been a pan down to the fleet of Star Destroyers, with the Super Star Destroyer flying in overhead. I think if we had that shot with a Death Star in there, that would be perfect for our edit of ESB.

Not sure if this would be useful, but on the ROTJ DVD, the menu features a shot of Luke's X-Wing and the Falcon flying down over Tatooine then going in different directions. It's a nice panning shot. Have y'all checked the ESB DVD for any useable footage from the menus?

And speaking of recycling things, if y'all find yourself in need of any small audio clips of Luke, the Rogue Squadron game featured some guy doing a very good impersonaltion of Mark Hamill. This is stuff like him talking over the comm in his X-Wing.
