It's been awhile since I posted a headcanon, and I've had this one kicking around for a year or so. I was going to attempt a fic, but I'm not writing anymore; though I still want to share the idea 'cause I think it's hilarious.
***This headcanon is completely Gen/Crack btw.***
So the idea is that AR1 (John, Teyla, Rodney, Ronon) and SG1 (Daniel, Jack, Teal'c, Sam) swap bodies. Either team discovers some Ancient Tech in Pegasus, with a similar set up in Milky Way (or vice-versa), and to see what it does, it needs to be activated simultaneously by people with a strong ATA gene. Hence the need for Jack to be there. Everyone present ends up swapping places with the other team.
- John is miserable and tries to hide in Daniel's office but Vala finds him and she can tell it’s not Daniel. So she drags him off to participate in some kind of crazy heist and she needs a getaway pilot.
- Daniel goes around touching everything in Atlantis like a kid in a candy store, and uses the opportunity to get petty revenge on Lorne for what happened on the Unas planet.
- Teyla uses Jack's authority to designate more resources to Pegasus cultures, and is able to resolve some long standing diplomatic tensions.
- Jack vanishes and uses the experience as some kind of break, he goes fishing and confuses the Athosians with his great cooking skills.
- Rodney scares the shit out of some Goa'uld or whatever enemy SG1 is fight at the time. 'Cause imagine "Teal'c" going off on a frustrated Rodney-like tangent over someone doing something idiotic, and having them cower in fear 🤣
- Teal'c confuses the hell out of the scientists, because "Rodney" is acting very quiet, calm, and is taking time out of his day to meditate.
- Ronon spends a lot of time in the gym sparring or working out −'cause lbr he's not in his body and he is probably very frustrated and needs to get that feeling out in a productive manner− ✨somehow✨ he encounters Pete and when Pete tries to win "Sam" back he gets punched in the face.
- Sam is fascinated by the experience and is in the lab with the other scientists trying to figure out the technology. The scientists wonder why "Ronon" is spending so much time in the labs, but don't question it 'cause "it's just another weird day in Pegasus"
I was thinking the whole thing lasts about 4 - 7 days before everything goes back to normal. Atlantis has the most calm relaxing productive time in ages, the SGC is on fire (metaphorically and depending on John and Vala's shenanigans maybe literally).
