If you're not opposed to a smut dystopia, Duplicity's very backtag friendly regardless of its size. Hits all your other requirements too. Jess is currently the only Marvel TV character but there are a handful of very friendly comics folk. I'd be happy to answer any questions you may have, provided you're interested. The current TDM went up just yesterday and the main navigation, if you want to look around, is here.

I can also offer Jess in a meme/PSL capacity, I love her and Matt's dynamic in Defenders.
