I don't think that we should be considering Mr. Gold and Belle based on Carl Ellie. They are clear similarities but much of the basis is one scene in one episode that mirrors Up. Compared to the overwhelming evidence for their other based on, Belle has just the clear based on sharing name (from movie) and story with Belle/Beauty. Rumple is based on Rumpel by name and story, the Beast by his relation with Belle and Skin Deep as well as the man behind the beast stuff and the Crocodile by consistent mentions by Hook until the finale and the episode The Crocodile. We don't really see anything in Up after Beauty it makes more sense for Belle, Gold and Gideon to be allusions.
