With Disney basically rehauling most of the rides/attractions at Hollywood Studios within the last few years (even my favorite Disney attraction of all time The Great Movie Ride) I think the Rockin' Roller Coaster is in need of a retheme or overhaul or in general. There have been a few themes thrown out in the last few years like Guardians of the Galaxy (which is already getting a roller coaster attraction in Epcot) and Monsters, Inc. (which I think would be a big mistake if that is the retheme). I have conjured up an idea for a replacement for Rockin' Roller Coaster in my head for the last few weeks and would be an Avengers themed coaster. In the case of there being two Marvel themed roller coasters in the same resort here is my case. The Avengers roller coaster that I personally think would be a great replacement would be (in Universal Orlando Resort's terms) the Harry Potter Escape from Gringotts attraction, the more superior intense roller coaster while the Guardians of the Galaxy rollercoaster would be (as of January 30th 2018 since not knowing entirely what the attraction would be but what I have heard it would be) the new Harry Potter indoor lesser intense roller coaster that is being built where Dragon Challenge (or in Disney's terms Space Mountain) once stood. You could keep the archway leading into the attraction by putting the Avengers "A" logo engraved into the top of it and say below the it "Avengers Headquarters". They would (in my mind) gut the whole attraction to build a new show building that would host a new more high tech coaster than we have now. The outside of the show building would look like what were getting for an Avengers attraction in Hong Kong Disneyland. I know the chances of this attraction happening are slim since Universal still has the rights to make Marvel attractions based on the characters you need for this ride like Iron Man, Hulk, Captain America, etc. But it would be a dang good replacement if this got green-lit and built in the park.
