Agreed. I've done that before, where I wrote my favorite version, then wrote another version which replaced the ending to the other one. Whether you want to repeat the same information or not is up to you. I'd treat it like they do in television- you know how they have the little cliffhangers before commercial breaks, and then you come back and they repeat it? Sometimes they just leave it out and continue- but the point is, if you don't want to repeat the entire story just for the ending, then maybe just reestablish the scene briefly. Like a "previously on Desperate Housewives"... only not that.
Best wishes!
