This isn't that radical, but I thought it'd be nice. it would require a few seconds of new footage.

In the ending, still cut it to be that Padme lives (thus removing her death with the over-dramatic chorals as well as Bail saying he'll take custody of the child), but cut the giving of Luke to Beru so that we don't see the last shot of them gazing at the twin suns. At the front shot of Owen being handed Luke, iris wipe to Padme's funeral, recut slightly (no gungans). What could work even better about it this time is that the little girl walking in the procession could be assumed to be Leia. Afterward, fade to Luke (around 8-9), working on a moisture vaporator, then turning his attention to the skyline. Iris wipe. Credits.

Also, Vader's Transformation would be handled differently. His retrieval wouldn't be shown, and his reconstruction wouldn't be interspersed with the birth of the twins, either. Instead, a single sequence would show quick shots of his reconstruction, each fading to black before going to the next one, until Vader rotates up on the medical table. Fade to black, have us hear wheezy breathing from ROTJ, until it slowly morphs into his familiar breaths.
