This to infinity and beyond!!
The fact that anyone believes there is some measurably significant portion of the Parks customer base that can pronounce "anthropomorphic" let along understand the term and think about the significance of if a ride in Park X based on that movie is better as opposed to the same ride only in Park Y is simply laughable.
Unless you are marketing a niche product, to a very specific demographic, you don't design or market to the extremes. You market to the masses. The masses want good rides, and shiny things to buy, and would love both to be based on something that they already know and like. I don't know if Zoopotia is that, Disney with their internal analytics would know better, but Moanna certainly would seem to fit the bill.
So if 95%, or even 90% of the market base doesn't think about where a ride is, as long as its good and they get to see their favorite familiar characters, why in the world would Disney spend additional time, efforts, or resources to just to get to that other 5-10%? Especially when your overall potential market base drastically exceeds the number of visitors you need to be profitable, and that frankly you can comfortably service?
If they go with Zootopia, here is what your going to see. Loads of shots of amazing rides and features from the existing parks. Social media post galore about "your favorite characters brought to life." You are going to see a Judy Hopps character standing right next to Mickey and Minnie, and no one is going to be talking about the anthropomorphic difference between the depiction of Mickey and Judy. All the morning news shows on ABC will be running stories about it, I can even see the tag line, the Animal World of Zootoia coming to Animal Kingdom.
Moanna is an even easier sell.
