I don't actually have all my characters and did the same as you.

Characters

Maverick
- Head student in the dark house (probably, or his brother). Low-key i think he'd have a rivalry with karter but would flirt with him and drew to get on his mothers good side. Probably a top academic, and would be rivals (temporarily) with Dawn.

Milo
- One of the top athletes in the light house besides Elric. Bros with Elric. Likely will end up crushing on Rowan. Hosts major parties.

Ivy
- Parents work for Maverick and she grew up with him and probably Sage. Have their little dark trio clique. In the dark house. Probs crushing on Sage but wouldn't admit it.

Tyra
- Either besties with Chase or just knows him and Andy through school. I don't know if she'd be in the light house or not? But definitely will end up crushing on Elric.

Anastasia
- Daughter of a prestigious family. Either her or Esme would be Head Student of the Spring House. Her family would probably own Les Fleurs Désirées though. Obvi has mad feelings for karter. I think she'd have siblings in this universe though.

Wren
- Son of a family who probably works for Drew's family. Grew up with Drew and def has a crush on her. Besties with Dylan. Idek what magic he'd have lmao.

Vienna
- Would be in the dark house. Probably wouldn't have many friends at all unfortunately. Rip vienna.

Ianthe:
- Attending another academy and is an exchange student with Eva to the main academy.

Echo/Eden/Kieran/Bruno:
- probably all know Dawn. Eden, Echo, and Bruno would be in the winter house. Kieran might be in the dark house. Echo would be an athlete, Kieran a loner, bruno a wallflower, and Eden would probably become an athlete.

Mathias:
- Is he the head or Maverick? I have no clue. Probably sticks with Tempest but would 100% be a jock and not as focused on studies as Maverick.

Henry:
- Head student of the fall house. Obnoxious. Obviously trying to date Anastasia. Prick.

Rhysand/Vera:
- They're technically twins. I think vera would want to be the head student of lunar more, but who knows.

Cato/Nova/Quinn:
- I never decided who was the oldest sibling, lmao. But one of them would be the head student. Probably not Quinn.

Houses

Dark: Power and Ambition
Fall: Tradition and charm
Spring: Beauty and
Lunar: Talent and extravagance
Tech: intelligence and control

Gem fae and all that would probably be under the tech house. If faes not their own academy thing then the different courts would probably fall into different houses.

Ideas/Scenarios

- Okokok so we have the main academy which all our ocs will likely end up at (we can just say it's an exchange program or something).
- There could be another academy for Les Fleurs Désirées, and whoever else. I think it'd be an all girls school. Very Beauxbaton vibes from it.
- we could possibly have another academy that the bartenders, assassins, would all go to /? And then the main ones have transferred over? If it was for spicy reasons it'd probably be because the headmaster wants them ruining the main school so people transfer to their academy. Idek
- Fae could be their own academy or they could likely find a way to fit into the other houses.
- Okay but imagine that The Les Fleurs academy thing comes over to the main academy and is all like, oh we'll show you some classes we host. And one of them would be damsel in distressing because that academy can't teach at all and is sexist or whatever. And everyone would be put in partners, and Maverick and dawn would still be rivals but he'd have to save her.

Notes

- im tired and the brain isn't braining. So idk what makes sense and what doesn't lmao.
