I have said before that I would prefer it over Ratatouille if this is the mindless direction Epcot is going and we can't do anything to stop it, but yes. It would be weird.
Don't really agree. I would say that Hunchback is clearly the most appropriate Disney IP to use, as it is really a classic French tale and greatly features the city of Paris and a major landmark of the city. I could even imagine an interesting pre-show or after show based on the Festival of Fools. But I'd agree that Disney doesn't seem to care much for that film at this point...
Of the remaining films, I think Ratatouille works better for WS than the likes of BatB or Cinderella. Ratatouille is based in the "real" France and celebrates a huge part of French culture -- the culinary arts. The princess stuff, while drawing from a cultural works, feel "fake" because of their fictional settings and don't have as deserved a place in a pavilion that (should) celebrates the actual country of France. YMMV.
Anyway, interesting to hear this rumor crop back up. I do also recall that there was talk about a new country actually being considered to be added.
