Took another jab at it. Made the Excavation coaster have a more realistic acreage. Before it was around 1.25 whereas now it is around 2.25 which is comparable to BTM.
Here's one without marked sightlines:

Here's a before and after gif:
And here's a V1 to V2 gif:
I don't really see the need to alter Dinosaur to a great extent. The area can be placed in Central America. The story can be slightly altered, making it a remote experimental facility in a Central American Jungle. The ride is already dressed like a research facility and is very isolated.
The excavation coaster is people looking for dinosaur fossils in a South American mountain. The mountain's aesthetic would most closely resemble the green side of mount prometheus in DisneySea picture below, while being substantially shorter.
The Indy ride entrance is an Aztec temple, which fits the Central American theme. I know the main complaint would be that it doesn't fit the Animal Kingdom mission statement of animals, but since Indy is focused on Archeology, so it could be a search for the Aztec's connection with a mythical creature.
Lastly, I realize this isn't the Imagineering section of the forums, but I just wanted to demonstrate the area's potential.
