Seconding - thirding? - the ZYL and John Sheppard lounging similarities. I'd love a crossover between the two, as well. The thought of a Wraith trying to feed on Shen Wei and just... failing and being very confused about it before meeting its demise courtesy of either SW or ZYL entertains me.

I can't say they remind me of any other pairings or fandoms specifically, but I do have a thing for more reserved characters with partners who poke and prod at them into being more relaxed and open, even if only with them.
