As impressed as I was by how the Avatar property was seamlessly integrated into AK's themes, I really don't see how Indy could fit into the park's thesis without serious re-jiggering. Animals in the films (I'm not including supplementary books of dubious canon) are generally either transportation or mindlessly-swarming obstacles to be avoided/defeated (snakes, bugs, bats, Nazi monkeys). It makes for a fun cinematic adventure, but it's pretty much the opposite of AK's more reverent and educational approach.
Of course, all my hand-wringing doesn't matter in the grand scheme. At least Rohde and Co have a stellar track record when it comes to maintaining AK's thematic consistency. I would just feel better if this was a genuine expansion instead of yet another sacrifice of a unique, animatronic-centric attraction.
