Um Sora did make it in Smash Bros. Also if it does happen now is possible since Disney is making Kingdom Hearts a Priority

It could be possible. Let's look at the concept as a whole. It would make sense I theory it would explained how the Beast knows anything about Maleficent, Jafar, The Evil Queen, Cruella De Vil, and Hades even though he never met them. But we have to take a few things in hyperthetical questions. 1. If the end result of Kingdom Hearts leads to Descendants then when did it happen? 2. Who murged the world's together as one in the first place. 3. Why did that person do it? 4. Wear are the Heartless, Nobodies and unversed and don't say there all on Isle of the Lost believe it or not guys that island isn't that big and even still they can escape easily and since darkness would exist in people's heart we would see them all over auradon Prep give Audrey's presence. 5. What happened to the door to light is it still around? 6. Would it be risky because uniting all the world's as one would mean all seven princess of heart are in this one world making it easier to catch. 7. How come we don't see any keyblade weilders. Um Sora did make it in to smash.

Well it depends on the Anime I would say most would be Shounin Jump. First I would not include DBZ cause 90% of the characters are op and once Sora beats someone like Frieza, Cell, Buu, or Broly none of the enemies be actual threat plus the only good out of Kingdom Hearts in Dragon Ball is a running Joke of Sora looking like a sayian. What Kingdom Hearts needs a series that is well compairable. Shows like Fairy Tail, Yu Yu Hakusho, My Hero Acedamia, RWBY, and Sailor Moon, but I say the best Anime for Kingdom Hearts has to have a main Protaganist as the who starts out as the underdog like Sora, who has a best friend who is also his rival who is popular and later fell to darkness out of jealousy of their best friend, and have a situation where the main protaganist is saving his best friend from himself like Riku. And travels with a loud moth who knows everything and has a bad temper like Donald, along with a goofy yet loyal and smart friend you can trust like Goofy. All while an organization is hunting the main protaganist to do to the power he possess. Well that's an easy Naruto. The show it's self have similarities to Kingdom Hearts, and hey the Actor who voiced Xemnas in Kingdom Hearts also voiced the Nine Tails in Naruto, the actor who voiced Lea/Axel in Kingdom Hearts also voiced Iruka in Naruto. Plus unlike Dragon Ball where they would force Z into the game. Naruto has plenty of retold stories and even so they can a story strictly made for Kingdom Hearts.
