I'm not sure if Zelena can come back or not, but I wouldn't hold my breath. You do make some interesting points as to why she might not actually be dead though. As far as Once not following the Wizard of Oz storyline, that is one of the main things of the show: they take a familiar story and twist it. It has nothing to do with copyright or any other legal problems, Wizard of Oz is in public domain anyway.
