There is a Middleaged ships comment ficathon over here.  According to the organizers, "As for the ship ages there is no upper limit so characters 65+ are definitely included. As for the lower age limit, I put 40+ in the rules, but this is not a strict rule, if one half of your ship is in their thirties go ahead and post them. The whole point of this ficathon is to encourage the creation of fanworks for mature adult pairings. I find in a lot of fandoms the teenagers and characters in their early twenties get most of the love, and in turn most of the fanworks are written about them, I am hoping to change that."

It's a little tricky with androids, but since Connor is played by a 30-year-old man, Hank/Con is probably fine.  HankVin certainly is, since Gavin is 36 at the time of the game.  Honestly, I suspect that Hank/almost anyone in the game would be welcome.
