No, I don't really have any non-canon pairings that I'm fond enough of to say they're OTPs. Pretty much whatever the original author says, goes.
HP is the only fandom I currently write for, though I have written fic for Pirates of the Caribbean, Star Trek preboot, Roger Zelazny's Amber series, Percy Jackson, The Dresden Files (books, not the TV series), pre-New 52 DC Comics, Big Bang Theory and one Marvel movieverse-Disney crossover that gets more love than anything else I have ever written.
I'm not really active in any other fandom, or active in any other way than writing fic, TBH. There are a few TV shows I watch or watched and liked well enough that I might could write fic for them, and a few more book series as well, but other than Harry Potter there aren't any fandoms (for things I'm interested in) that are active and organized enough to host fic exchanges and fests.
Of the fandoms you have listed, the only ones I'm familiar with at all are HP and Castle. I don't even know what AtlA, PJO and ASolaF are.
