The ending of Mad Max Fury Road was basically what I’d imagine a Gary Kurtz-style “bittersweet” ROTJ ending to be. Just substitute Nux with Han, Furiosa with Leia, and Max with Luke.

At least, something like that was probably Kurtz’s idea for how to wrap up the OT in one film. Had George Lucas kept to the idea of an ST that introduced Luke’s lost sister, probably Han and Leia would both have been killed in ROTJ (as Lucas indicated in interview in Bantha Tracks: the sequel trilogy “deals with the character who survives Star Wars III”, meaning Luke).
