If you go back to some of the original concept art for DAK, it featured a wooden rollercoaster (and a large one at that) in Dinoland. As I recall, it was themed around a large dig site. If I could imagine an overhaul of Dinoland, it would be that concept for the coaster (a Thunder Mountain-esque ride).
Then I would bring back the Dinosaur Jubilee fossil museum concept that was featured when the park opened, but make it a real building and not a tent. Theme it to the Dino Institute.
So then you have the "classy" Dino Institute with Dinosaur and a large, state of the art, indoor museum; plus the more rag-tag Boneyard and The Dig Site coaster. Finally, plus out the Cretaceous Trail, making it a true walking trail with "discoveries" and animatronics around the corners.
