Maybe it's because I spend a lot of my time in the SPN/HP crossover sections but...most of the crossovers I come across now a day are more bias toward the other show/book/movie that is being crossed with SPN. I've seen too many summaries that read: Harry Potter is actually Death's Master or something like it. And I'm getting a little tired.

So can someone please rec crossovers that are more bias to Supernatural? As in Sam and Dean have heavier focuses in the story and are not sidelined or cast as love interest for other characters? Any crossover is fine. I watch a lot of TV and read a lot of books so chances are I may know a few of the TV shows/movies. The only thing that's really a must is for the Winchesters to be main characters of the story (AKA important roles).

Any self rec is fine. I don't mind any length and while I prefer to avoid WIP stories, I don't really mind them either if that's all you have.
