I really like @802pov's Reverse Siblings AU, and I had been wanting to make some fanfiction for it. Obviously, reverse Dipper and Mabel will have to have different names, so when the AU was just getting around, I told the creator that Dipper and Mabel could have names like constellations or something like Mabel’s name. So Mabel could be Lyra (which is a constellation) and Dipper’s real name could be Labem and his nickname could be Orion (and maybe everyone could refer to reverse Dipper and Dipper as Big Dipper and Little Dipper).
And then, this got me thinking, well maybe it doesn’t have to be just Dipper and Mabel. We could include reverse Pacifica and Gideon just to make it more interesting (and to also give reverse Dipper and Mabel some enemies as well). Heck, we could even include both Bills.
So reverse Pacifica is the embarrassing older sister of canon Pacifica and reverse Gideon is the sweaty, awkward, extremely embarrassing older brother to canon Gideon (it would almost make you think that everyone was switched at birth or something).
And then reverse Bill and canon Bill would be “brothers”. Reverse Bill would be like a servant to reverse Dipper and Mabel and Bill would be the one to try and traumatize everyone. Reverse Bill would also try to convince Bill not to start the apocalypse.
Everything would happen the same, just add in the reverse characters to make things even more interesting.
