So I got bored and pondered hwo they could put some form of the Spiderman coaster in Shanghai at Avengers Campus in place of web slingers. Behold: My rough plan on how they could pull it off:

The red track represents the forward portion while the yellow represents the backwards. As you can see, if they are willing to forgo the Dr Strange mini show, there is some space for some track. Perhaps if you get a little more creative with the layout, you
could squeeze more track in there. I just personally like helixes. The blue represents the building as some of this would be indoors and the green represents the queue area. While it would be shorter than Shanghai's, there is space to put a family coaster that DCA desperately needs.
Just wanted to throw this out there because I want to demonstrate that there is more space to work with than people think. Heck, you could utilize the Disney Junior space if you wanted to! Also we can do away with Web Slingers. Oh and that random long box at the loading area represents the length of the coaster train. Borrowed that from the IncrediCoaster's length for reference.
