I definitely had the thought while watching the movie that parts of Ta Lo and especially the animals there seemed not that far off from Pandora's look (the Ta Lo deer creatures were the most similar to their Pandora counterparts). I don't think they would/should combine the two, but I also feel like they might be too similar to have different areas for them.
Also, while Pandora's movies had conservation as a main theme of the movie, making them more applicable to DAK, the creatures in Shang-Chi (as much as I loved them, especially Morris) were definitely more side elements. I'd love to see a Shang-Chi attraction in the parks, but I think I don't think DAK is the right place. Maybe they could transform the Animation Pavilion in DHS into the courtyard from his family home or something like that and then have something with the forest inside the building somehow. A stunt show would be amazing, although they probably wouldn't have two of those in the same park if Indiana Jones is ever going to return...
This is how I feel. The land could be nice but I don't feel it was really fleshed out enough to fully warrant a land, and while there were interesting animals and creatures there, hardly any of them even got named let alone played into the plot. They were mostly just there in the background to look cool.
There have been rumors that the Finding Nemo musical might be closed for good now. With it's location right next to Primeval Whirl's former spot, it and the Dinorama section together would be enough space for a new land. It would be nearly the size of the remaining Dinoland area. With it's proximity to the Asia area right across a bridge they could put Ta Lo there if wanted.
(EDIT 9/16: Just saw where they announced the closure of the Finding Nemo musical, but that it will be replaced by a new Nemo musical show next year so guess that takes out that space for an expansion area with the Dinorama area in the near future.)
Personally. I'd prefer any additions to Animal Kingdom for lands be based on real places. My ideal plans would be to turn the entirety of Dinoland up through the theatre in the wild (theatre being removed) into South America. Many dinosaur fossils have been located there so could still maintain the dinosaur section in it's current form for the most part and give it a more archeological edge and add a few new scenery elements to feel more South American, and then convert the Dinorama/theatre area into a rainforest themed area based on the
Amazon. There would be plenty of opportunities for new animal encounters here and rides themed to animals and the rainforest.
Another new land I'd like to see would be Australia added in the empty space between Rafiki's Planet Watch and Asia. The train station could work for both areas, just need to work in some sort of footpath to it from the rest of the park as well. This could then include lots of animals from Australia not featured yet with an aquarium space for the great Barrier Reef. Can relocate Finding Nemo musical to here if they wanted, similar to FoLK moving to Africa. And incorporate that IP along with Rescuers Down Under.
These two additions would fill the park out pretty well then covering most areas and adding more rides/attractions to flesh out the parks line up as well.
