Capcom owns Monster Hunter, Level-5 owns Yo-kai Watch and both franchises were farther from Kingdom Hearts to SE yet the collaborations were done. It's a matter of decision between both sides but I would assume Kingdom Hearts is an easier matter as Kingdom Hearts is developed and co-published by SE.

A collaboration could bring gear, minions, bardings and an event. It's a different matter, as for one, I would enjoy having a cute Kingdom Hearts Heartless minion following me around.
