The clause that mentions the character schedule also includes future characters. That schedule defined who Universal would be able to use in developing the land, it did not lock down the families that were used. A big summer blockbuster establishes a large public connection. I know there is precedent that would agree that Marvel decides what is and isn't, but it also seems crazy that Disney could do something as simple as move a character on a spreadsheet and end Universal's rights. And regardless of whether or not the argument would fly, why not at least give it a try?
