If a third-gate that's well planned, with a fairly high budget, was added to the current two parks after the WDS development then it would rank DLRP among the best theme park resorts in the world.

Over in France the popularity of the brand is nowhere near what it is in the United States and United Kingdom, so it's important to only chose the most recognisable characters from the brand.
It would also be good, as said, to use the Incredibles and some other Disney/Pixar characters of that ilk.
A Land of Heroes would work especially in the long run. What happens if Disney loses the license to Marvel like how they did with the Power Rangers? (I know, terrible comparison, but it's similar). It would cost so much to retheme an entire park.
Personally, I'm against having Marvel in Disney Parks. They don't exactly fit in as much as we'd think it would. The Disney Magic kinda conflicts with the vibe of Marvel.
But it should be handled similar to Star Wars if it does end up in Paris. A ride here or there, plus a few characters and/or a parade. Or a large part of another park like Carsland in DCA. Or part of a Hollywood setting.
Not to mention Captain America who, lets face it, would not fly in France!
Those marvel superheroe comics have not nearly the clout in Europe they have in America. Rather unlikely that they would provide the themeing for an entire new park at Paris if such a park is ever going to be built.
BTW, my family and I love Universal Studios in Florida. It's our favorite vacation spot. And the Marvel area is one of our top three areas -- especially the Spider-man ride. We don't care for Disney too much (too kiddy for us), so we'd hate to see IOA lose Marvel.
As you walk up to the table, it is obvious that there is no one around.
The moment you touch one of the items on the table, a group of superheros jump out from nowhere and beat you up.
You could call it "Marvel-verse and the Forbidden Table".
I'd honestly prefer them to add more, high quality, attractions to Walt Disney Studios Park before going off and making a new park.
If the proposed Ratatouille dark-ride is added over at WDS, then I'd be happy to consider a third gate.
