No even though Donald is one of my favorites unless Mexico is populated by singing ducks he doesn't belind there.
Figment is different he was an original character created specifically for Epcot.
And should Epcot not celebrate the creativity of the WS countries? As it turns out, the Snow White faerie tale was told for generations in Germany before the Brothers Grimm catalogued it. It could be argued that this enriches one's understanding of German culture. Not that most will "get it" in this regard, but that's one of the joys of a Disney park. It works on several levels.
I feel somewhat the same as you about Donald in Mexico, as he is not a part of Mexican culture. Plus, frankly, I don't think that makeover was done well.
I'm guessing you don't much like the Kim Possible adventure, as Japan is not actually menaced by robot terrorists and Dr. Draken doesn't actually maintain a lair in Mexico. :shrug:
