Absolutely. As I have often mentioned on here, I would love to have a ride that is basically the first part of JRA but longer and that's the ride. Just a sedate boat ride seeing and learning about dinosaurs.
So my point is that there certainly is the potential to do something like that and differentiate a "dinosaur land" from what exists at Uni. Were I to run Disney, I would add to Dinoland and create the family friendly ride (picture something like UoE's dinos) to compliment Dinosaur (the ride) and make a dinosaur based land that is distinct from Uni. But disney doesn't generally seem interested in doing that kind of project any more.
