If the sequel does well then yes.
I think AK is desperate for rides and adding two if not more rides to the park and hopefully a great restaurant will go a long way to boost attendance and give people something to do. Plus an indoor boat ride that blasts the AC will be huge no matter what movie/topic they explore. I also think that even if you are not a fan of the movie, riding on a dragon-like Banshee could be amazing if given the right technology and people will not care if its avatar or downtown NY- flying through the air is still awesome if done correctly.
Plus, I think the night time show, night safari, and enjoying the park at night will keep people there longer too.
I just wish they would add some other rides to (Mystic Manor, please) and some additional restaurants. I think when Pixar comes out with The Good Dinosaur and they replace the eyesore known as Chester and Hesters with this movie, the park will really round out.
