so plot 1: basically just Stefanie waking up as fem!Harry just before sorting in PS and fking the plot up. Bonus points if she's a Ravenclaw (we need more rep than just nerds y'all) & still besties with Ron who also goes to Ravenclaw with her(I feel his chess strategies would be more appreciated there).
Pairing could be a well written Cho Chang or an OC. (Bi Steffie supremacy)
Plot 2: this one's a bit complicated but basically we know Damon also slept around when he was human and so he had a bastard with someone, which is whom Lily Evans is descended from. Oh Lily is adopted by the Evans btw. So sometime during her tenure in Order, Lily decided to do a family line test and got to know the Salvatores siblings being alive somehow and decided to meet Stefanie (that's who she was able to contact but Damon was out of reach) and kept in contact.
When the whole secret keeper switch happened, Lily out of paranoia decided to contact Stefanie as a backup plan incase something happened. And basically a portkey would be activated that'll send Harry to Stefanie.
Because Sirius was busy with Order, they weren't able to let him know sooner and the day they were about to (which is why Sirius was on his way there), Voldemort happened. Due to magic shenanigans, the portkey activated a little late, so after Voldy died.
The second one could be normal or WTM type. There's also something related to Stefanie that I wanna explore wrt her relation to Silas (or Silvia here)
The Apollo one is pretty easy, Apollo had a soulmate back in ancient Greece who was either fem!Silas or Silas' twin (who was also Nyx's daughter), but as his romantic fate is she dies and gets reincarnated as Stefanie Salvatore. The twist is that Apollo is punished to be mortal for the meantime (thnx Zeus).
Could be PJO or just rl Greek mythology.
