>>33611117The best way for them to return would be much later on in SM to have them help with establishing Gyms or to talk with Mallow or whoever has interest in becoming a Gym Leader about how to do it. That or to have them appear with Delia at the end of SM for Ashs graduation ceremony.
Mallow seems like the one who has the most likely chance of becoming one since she doesn't need to travel away from Aina Cafe and can run it alongside being a Gym Leader.

It's a role thats exclusively for the main heroine and right now that's Mallow.
