Back to a re-theme of Dinosaur to an Indy theme-
Dinosaur is constantly a 10-20 minute wait while Everest and Kilimanjaro (both of which are significantly higher throughput rides) have much longer queues every day. Meanwhile the other two Disney Indy EMV's are the star attractions with the longest queues at their respective parks. Dinosaur simply isn't up to the standards set by the other two EMV's even after this refurb. Most people here seem to come to a similar conclusion that Dinoland is hot garbage (which it is), that AK needs another continent with animal exhibits (they do) and that a South America re-theme for Dinoland is a great way to solve both issues.
Indiana Jones is an archaeologist who deals with the supernatural, it would not be a stretch AT ALL to see him looking for some sort of artifact in South America relating to animals or even Dinosaurs (similar to Everest). There's a thriving paleontology community in South America. I know wonks would lose their minds at mixing paleontology and archaeology but honestly most people are too simple minded to question or understand the differences anyway.
I've been wanting them to do this since before Chester & Hesters was even built. Heck, you could even keep most of the Dinoland stuff and have it be Sallah peddling Indys "artifacts" (cheap trinkets) in the stores and charging people to see/ride excavation equipment like Primeval Whirl. The boneyard could remain exactly the same. Besides Dinosaur itself, the rest of the land would only need a light re-theme.. Toss in a trail with some big cats, snakes, sloths and birds and you've actually got an excellent "new land".
Of course the other direction that would be easy to go is to make the area Australia. Plenty of dinosaur/paleontology stuff there and then Nemo would be appropriately located as well. It could still be an Indy theme based around some Australian artifact and you could still use the Sallah/excavator equipment overlay too.
Either way, I'd LOVE to see Indy find it's way to Dinosaur- but ONLY if it's a full fledged re-do to the Disneyland/TDS version and not some cheap overlay with 1/2 the theming (which sadly I could see happening).
