I would say that Neverland is finished, but Oz, Dunbroch, Arendelle, etc, could all be possibilities. They would not have to necessarily use the main characters from those areas, but could reference them as existing while focusing on other characters (and character mashups).

Oz, in particular, seems ripe for possible spin-off, if they wanted to go that way. They've got Dorothy and Red set up already, and there is a lot of the Oz mythos that has yet to be touched. They could cross Zelena in, if they wanted. And they could easily work other stories into that realm, if they wanted.

I think the key is that last statement. "If they wanted". The demand for another spinoff at this point is not high enough to warrant ABC spending the money to film it. While Once is enjoyable, it is not NCIS or Law & Order. While the options are there for Once, the demand is not.
