After my last visit to AK in February, I actually quite enjoyed Dinosaur unlike when I rode it in 2016, where it just felt like a dark, boring version of Indiana Jones. If they do add more Indiana Jones to the theme parks, I hope they move it to DHS where it can be next to the stunt show, or replace that area entirely. I would like it to be similar to the Indy ride in DL, but I wouldn't be opposed to a mine train roller coaster akin to what other parks have across the world. Coasters have evolved so much since Disney, with them going backwards/launches/etc, and being able to tell a story (7DMT, EE), and not just be thrill rides. I can only imagine a mine train ride similar to 7DMT, but through a temple that features animatronic Indy and new screen technology like NRJ or the Universal rides.
With the addition of an Indy ride to DHS, I think that park would really become a multiday visit, though with the additions of Star Wars and Toy Story, it feels like it might still be but Indy would really put it over the top.
ALSO, if anyone is ready to be the next Indiana Jones - it has to be Chris Pratt and it's not even close in my mind. Unless they want to give it to Alden Ehrenreich.
