Question about Fandom Pairings

I'm trying to write another story with a subject rarely written about (like Visions which is a story about blindness) but I want to use another band then My Chemical Romance for it and I don't really want to write an original fiction.

Do people still read Fall Out Boy fanfiction? Or is it used a lot on this site? I wanted my next story to be written from the perspective of Patrick Stump with Pete as a secondary main character (as much as I can say without ruining the surprise). Is there a fandom for that? Cause the My Chemical Romance once is pretty big but I rarely see ones about Patrick/Pete. Plus, it's an old favorite pairing and I would love to make my way back into that fandom again.
