I still think the best way to incorporate Indy into AK is for him encounter a civilization in the jungles of Asia or South America, that worships, Dinos...which he finds are still living in the "modern" world as they have either been hidden away in an underground realm or on an island etc. This way, you can get rid of Chester and Hester, keep Dinosaurs, bring them back to life without going back in time, and can add a super immersive land they kills us all with it's pure awesomeness. And since he is there to study a civilization and only discovers the dinos by coincidence, you can have this without rewriting Indy's character or what archaeologists do.
