Potential Fandoms? (Patreon)

So in preparation for my next story poll (my second story for this month is underway and should be done by Saturday) I thought I'd pick people's brains about potential series they'd like to see me write about. Feel free to comment specific pairings if any come to mind. This is a mixture of things I've never written before and also series I've heard about but don't actually have first hand experience with.
