Fandom PSLs

Looking for an MCU psl with a slight twist: I'm getting a little tired of exploring post-Civil War fallout, and I'd like to brainstorm some kind of AU to play around in. Dig into those good old fanfic tropes. (Something that has enough teeth for us to get a little plotty with it, so maybe not a generic coffee-shop AU thing.) I have a few ideas, but I'd like to go back and forth with somebody who's interested, who enjoys world-building, and threading where the tags generally average out to three paragraphs, because I like a partner who gives me something to work with.

I'm open to almost any pairing - my favorite kind of person to write against is someone who feels really passionate about their character! - though I have well-documented weak spots for Barnes and Barton. Hit me up if any of this sounds good!

Somewhat off-topic, but is there an appropriate comm to take interest checks and hash out fandom comm ideas?

i would love to fill one of the marvel or harry potter lines listed here! especially if you're interested in action scenes and high stakes plots.

Hoping to find someone to play Petyr Baelish against my Sansa Stark. Show-verse strongly preferred as it has been some time since I read any of the books. We can do something that sticks to canon or go a bit AU and create our own story for them. I'm really looking for a writing partner that I can brainstorm with. The line would have smut involved, but also plot and substance as well. Journals only please
