Avengers crossovers

[heterodynegirl.livejournal.com]

So, having seen this amazing art of awesome, (itself based on this fantastic graphic,) I'm craving some fic to go with it! 

Basically, I'd like the plot of Avengers in an SPN AU. Expanded on below Translation: The Avenging Angels [for lack of a better term] are dealing with Tom Hiddleston!Lucifer bringing on the Apocalypse by way of an invading alien army.  

The Avengers don't have to be the angels as determined by the art/graphic, but it does seem to have assigned each of them fairly well.

Super-bonus points for Sam, Dean, and Cas being included somehow, but no Wincest or RPF/RPS, please. Dean/Castiel is quite welcome (and in fact, preferred,) if they appear.

Really, anything Avengers/SPN would be awesome; it doesn't have to be based on the art linked above. Note that I've already read everything non-Wincest or J2 linked on this page.

Also particularly welcome: anything with Avengers!Loki meeting Supernatural!Loki, à la this short comic.

While gen is totally fine (and depending on the setting/AU, possibly preferred), the pairings I'd rather for the Avengers are:

Tony/Pepper
Clint/Natasha
Thor/Jane
Bruce/Betty
(optionally)
Steve/Peggy

Note that any of these are fine as gen, too; I'd prefer no contradictory ships, though, if possible. (Knowing the fandom's propensity for Tony/Steve, that may not be.)

I hope this doesn't seem too demanding? I'm really not as picky as I sound, I swear.


Note to mods: there doesn't seem to be a crossover: the avengers or crossover: avengers tag, so I'm tagging as crossover: iron man & thor.
