What Bingo said.

I'm not sure if this is possible, but it would be great to somehow have Luke doubt the future of the Jedi, now knowing the truth of his heritage. An ending where he decides to bury his lightsaber, and trust the galaxy to continue without the Jedi or Sith might be interesting.

For single trilogy/non-definitive, one off edit, flashbacks in ROTJ could be interesting to explore aswell. Generally ROTJ edits leave it quite lean at 1.30 or less, so maybe this could bulk it up.
