If not Oz, then Arendelle. Or since many people seem to want either or, they could mash them up. Like I mentioned in another thread, Santa Claus exists in Oz, because the author wrote a "biography" of Santa and gave him cameos in the Oz books, and Arendelle is associated with Winter through Elsa and Ingrid's powers.

Santa could be a villain that threatens Oz and Arendelle, and Glinda finally escapes from her Winter Wonderland and teams up with the Arendelle heroes. And we could finally get Olaf in the Once-verse.

That sounds really dorky and crazy, but if they can pull off Warlord Bo Peep, I think they could pull this off. Plus, a Christmas-themed spin-off to air during the Winter Hiatus? That'd be pretty awesome, let's be real for a second.
