I would happily take GotG over Indy. Just make a great ride Disney, no cheaping out. Especially since it's pretty much the only thing Marvel they can use aside from BH6.
theres hardly any BH6 content in WDW.
They can use GOTG? I thought that it was tied to the Avengers in the Comics and for that reason they can not. Based on the movies the story arch is attached as just with the infinity stones.
Some Avengers have been IN the GOTG group (see Iron man in the first part of the Vol3). Also Symbiote Spiderman ( Flash Tompson) for a bit as well.
Captain Marvel and other chars meet and helped in vol2 as well.
But the original guardians were billed "Tomorrow's Avengers" (as in the avengers of the future). Captain Vance Astro supposedly had the original Captain America shield.
