Honestly, Moana and Coco are high on my list. Moana for MANY MANY MANY reasons such as the whole heart thing perfectly fitting into the Kingdom Hearts storyline, the fact that Moana and Sora are both islanders, Maui and Moana would be great party members, and lastly the fact that the whole sailing concept is definitely possible thanks to KH3 and if you combine sailing with the constellation gummi ship function in KH3 as well then you'd have a great Moana world. Coco though, itd be a perfect opportunity to give Sora a new world look by turning him into a skeleton and maybe Donald and Goofy becoming skeletons too or better yet alebrijes. Sora has played the ukelele with Stitch numerous time, clearly Sora is capable of playing the guitar too alongside Miguel and Hector. The whole comical and loving atmosphere of the entire Coco film would perfectly complement Sora's overal childish and caring personality. Also, much like the Colosseum's in the world of Olympus where the heartless entered the Colosseum's games, I can imagine heartless entering the music contest in Coco and Sora has no other choice but to compete in order to help Miguel win. The overal lesson Sora can get from this world is that Sora, despite already holding everyone near and dear to himself, can learn to never forget and love his friends and MAYBE Sora will then remember back to his family that he straight up forgot about in game 1 and still hasn't made any attempt to remember them. Seriously Sora, you had a mom and yet you're more concerned with Riku.
