Do you think that the characters on Once Upon A Time could start doing meet and greets at WDW? Would you even want them to? With the shows popularity I could see it as a possibility. They could have the Disney versions of the character but could also have the OUAT versions of the characters in the parks. Rumpelstiltskin and Emma Swan don't appear in the parks at all so that wouldn't be an issue. The OUAT versions could look like this, which clearly looks different than the Disney version.
