How Likely Is a Moana Land at Animal Kingdom?

Because it's Earth Day and Animal Kingdom's 25th birthday, I thought it'd be a fun time to speculate and read into some concept art.

Ever since Josh D'Amaro stood on stage at the D23 Expo back in September and teased the possibility of a Moana/Zootopia combo land that was being considered to replace Animal Kingdom's Dinoland U.S.A. area, fans, and theme park watchers alike have been wondering, could it really happen?
