My theory as to why Oz has yet to make an appearance on Once Upon A Time is that the creators were waiting for the release of "Oz The Great and Powerful". Since the film is a Disney property, the characters and settings are ones that can be used in the future on Once. Personally, I would not mind seeing Rachel Weisz as Evanora drop by Storybrooke and becoming an arch nemesis for Regina. Or to Mila Kunis show up as the Wicked Witch of the West.
