If Disney would do something like this (and I don't think they will), it would be a huge change in the way they theme their resorts. Historically, the in-your-face character/movie theming has only been done at the value resorts. The deluxes and moderates get more subtle theming. I cannot imagine a deluxe resort getting plastered with comic-book imagery. Not to mention, they do major convention business at the Contemporary, and I don't think superhero theming would go over well at a $300+/night resort that's hosting C-level executives.
That said, the Marvel and Star Wars properties are the hottest thing in the movie business right now, and I wouldn't be the least bit surprised to see a new or re-themed value or moderate with a Marvel or Star Wars theme. I know they're building the Star Wars resort, but that looks to be a high-end entertainment experience, not a traditional hotel, and I expect them to capitalize on the popularity of those properties any way they can. They'd be foolish not to.
