I'm going to try to address this list in a semi-linear fashion, since my reply kept getting confusing.
First list:
1-3: These are fun, I like 1 particularly, and 2 is *fans self*. Good short fic potential.
4-8: My feelings. 4 and 5 hurt so good. And 8 is amazing. I can definitely imagine Callan trying to make Meres kill him instead. I'm not crying; there's something in my eye. I would definitely go the happy ending route though. Meres, of course, griping the entire time about the loss of his ritzy flat and fancy car (but secretly happy because Callan > The Section >>>>> his crazy aristocratic family): this is the truth and I love it. In fact I would be sorely tempted to set a story during that "retirement", and have everything that led them there be nightmares/flashbacks. (In fact it might be possible, that way, to have one's cake and eat it too- some of those nightmares could be about how badly things could have fallen out instead).
Also, I was thinking about a "Death of a Hunter" AU myself, one where Meres won't leave when Callan first gets hit over the head, so they end up both getting taken together. But it is very interesting to imagine the roles reversed, with Meres hospitalized and Callan the one trying to pick up the pieces (probably with Snell all over him).
Second list:
1-7: Good short fic potential with all these too. I'm especially drawn 4 (I guess I'm into jealousy with this ship). 2 also has fun cracky possibilities, if everyone in the section is just trying so hard to ignore it for plausible deniability. But yeah, these are all great.
8: I've actually got something like this already in the works, though I will probably wuss out on the actual character death because I'm weak.
9: Oooh, this one has promise too. Maybe as a 5 + 1. You know, 5 times Lonely was a total cockblock (and/or whatever the emotional equivalent of a cockblock is) and 1 time he was still that but also somewhat useful.
10: I actually have two of these in progress as well, one with Snell and one with random bad guys who have Meres. So great minds think alike. This fandom does ask for it, though, doesn't it?
Crossovers:
1-2: You know, I think Meres and Villanelle could be bros if they came at each other from the right angle, but otherwise yes. Disaster. And 2 is very cool too.
3: Oh, I love this one. Bunny would probably end up with Callan in the confusion and then spend the next while both baffled and terrified while Callan attempts to make a new plan with what he has- but Lonely would probably a) think Raffles is Meres and b) continue thinking Raffles is Meres in the face of protests far longer than reasonable. And then Meres would get sent in as backup and really turn it into the last act of Twelfth Night.
Anyway, I'll definitely try my hand at a few of the possibly-shorter ones and add some others to my to-write list. Let me know if you want to know which ones for sure or anything, while I let things percolate for a bit.
