If this happens, I think it means that the Indy show is not long for DHS. Think about it. If the Indy show was staying, then a new Indy ride next to it makes the most sense. If they are getting rid of the show but still want Indy to have a presence, then converting Dinosaur saves them money.
I am not sure Indy fits AK but if they bring a South American land (like another poster said) could make sense with Indy as a part of it. Then DHS gets a brand new land and AK gets a much needed improvement over Dinoland. They will probably bring the Indy ride from Paris to replace the dino spin coaster (forgot its name). Although I heard that ride is very off the shelf and and uninspired.
I like Dinosaur but if it means getting rid of the garish Chester and Hesters, I say bring on the Indy!
