I've always loved the idea only one death star.
I'd love to see the DS explosion at the end of Star Wars changed so that only one half of the thing blasts leaving the rest a burned wreck. Then in Jedi we find out that they're rebuilding it, and still it's a surprise that it's once again operational.
If you're looking for some ideas on a fan edit of Jedi, I got some in my signature. Seems to be in line with the ideas your thinking of.
