I'm excited to see what Imagineering comes up with for Infinity Defense in Avenger's Campus. But what I really think guests/fans would get excited about in Avenger's Campus in a themed roller coaster. DCA only has one roller coaster and it's not really themed...but that's what would make this park feel more complete (and worth the same ticket price as Disneyland, which has three themed coasters).
I think that a Cosmic Rewind scope of coaster would be possible using the underwhelming Web Slinger building for the entry/queue and load/unload. An elevated launch tunnel would race above Pym Test Kitchen inside a translucent blue tunnel with Spider-Man hex pattern, providing kinetic energy to the land. The gravity building would be behind/east of Mission: Breakout, requiring some backstage services to be relocated and a reduction of the access road.
Here are some images showing this location, plus a comparison of Cosmic Rewind, and an image I used ChatGPT to create of the proposed elevated launch tunnel.
I'm interested in what people think of this idea.
