My initial reaction is, DHS would be so much better for this. But then again, Disney made a lot of effort to explain how Pandora fit into Animal Kingdom and their reasoning had a lot to do with the conservation/harmony with the land message. And imo it actually works and Pandora is my new favorite Disney hangout. I don't know how but maybe they can somehow make this fit too??? Maybe the land will be populated with lots and lots of snakes... Anyway, dinorama needs to go, but I would prefer they just upgraded the land and kept it dinosaur themed and put Indy in DHS.
But it's easy to see how Avatar could fit into Animal Kingdom(it's lifelike, the themes are about conservation of nature, etc), Indy just has no connection no lifelike nature, or conservative, or any other theme that could work at Animal Kingdom.
