The way Disney was cross promoting Zootopia with Animal Kingdom it seems like it's just a matter of time before this happens... The cast all did press interviews from the Animal Kingdom lodge, there is a "thank you" to Animal Kingdom in the credits of the film because in the "making of" feature on the Blu-Ray they explain that their first step toward doing research for the movie was going to visit the Animal Kingdom park, and Rafiki's Planet Watch also had a small tie in exhibit with the film when it was first released in theaters, and Zootopia is basically just a "buddy cop" detective story, which they could easily do endless sequels to, so like Star Wars, Toy Story, and Cars, it's something that will hang around for a while
I think Animal Kingdom could use a "Fantasyland" type of area anyway, and then they could finally build a proper Dinoland. Plus they could also use a replacement for that great afternoon parade they used to have, and Zootopia would fit into that pretty well with that song Shakira did for the movie
