I think makes more sense if they build a Zootopia land in the EPCOT. Could be the first of a whole new fictional geography locations, eventually also Wakanda, Asgard, Olympus, El Dorado, Atlantis... you name it. (okay I'm only dreaming right now).
But seriously, is not because there is animals in a movie that it need to go to Animal Kingdom. I would love see a Zootopia new land, but I simply don't understand why people NEEDS it to go to Animal Kingdom. Why that fixation? Zootopia characters are human-like people that happens to look like animals-- there NOTHING about nature in the movie, which is the theme of DAK. The movie message is about respect different kind of people and cultures, which is the same theme of EPCOT. Zootopia is a name of a city, which also is the theme of EPCOT: you are visiting teasers of different location of the worlds.
If it will happens, anywhere but DAK is a better place for it.
