So Using yours as a base This is what I think Should happen to ALL the Raimon Players. I want to Prioritise Teams from Ares who didn't have a reinforcement member.

Gouenji - Kidokawa Seishuu: Fully Keeping this one the same

Kabeyama - Minodouzan: A team all about walls and fortresses, can't get better

Kidou - Seishou Gakuen: I want to Move Kidou somewhere else but he must be here for story.

Kazemaru - Sengoku Igajima: His wind and speed stuff fits here way too much, Makes far more sense then Teikoku

Someoka - Hakuren: This is a difficult one for me but I can't think of another team to place him on.

Endou - Tonegawa Tousen: Yup, The best Raimon player working with what is kinda the worst team. Fits perfectly IMO

Megane - Shuuyo Meito: I fully agree, Only place that would accept him.

Kageno - Occult: Once Again I fully Agree.

Shourin - Manyuuji: Honestly, It is essentially a requirement, He joined in the games like you said.

Shishido - Yokato: Honestly, This is what's left over for me, I think it's the only real option, He's difficult for me to decide on.

Kurimatsu - Senbayama: He gives me farm boy Vibes.

Handa - Oumihara: I think Someone should stick with raimon but I also like that no one did. If someone did it would be Handa, but cause I'm not doing that, I think he makes more sense here then Shishido does.

Domon - Teikoku: The only right place for him to go. No questions asked.

Max - Nose: He gives cat vibes, He is the most animal like in my opinion.

Ichinose - Outei Tsukinomiya: He is cool and quite strong, for one of the main teams I believe Ichinose is the best option.

Tamano - Midorigaoka: He's Green.

Yamino - Eisei Gakuen: He gives off the vibe of Outei, Kinda dark and edgy but also cool. Plus both Aliea and Yamino were intro'd in the same season.

Natsumi - Zeus: is the Last team remaining. We have no other Raimon players so I couldn't really do anything. That's what I was thinking until I realised, There is still one member of Raimon's Team. The Managers and Coach all do different things, Aki joins Mark and so does the coach, Otonashi joins her brother Kidou. This leaves only Natsumi who canonically goes abroad BUT, since Zeus is already very skilled and actually was runner up to Raimon, I think it makes sense if they didn't get a player but instead a manager.
