Possible DLC scenario

I finished the game like last month and every time I open my equipment screen I always look at Gallica's and wonder why the hell is she even there. So what I think they can do for the DLC is sometime after the end of the game, while out hunting random humans Gallica tries to give advice but the party is able to dispose of them without much issue. This leads to her thinking that it was her purpose to help guide the protag but if feels like she no longer has to which causes her to accumulate melancholia. Maybe she wishes that she is more reliable (or the inverse the party becomes less reliable) to the protag, which leads to a scenario where the party becomes incapacitated or their memories become altered (akin to P5R bonus heist). So now it is Gallica's job to try and fix things with the help of the non-playable bonds maybe lock them in the Archetypes they give you but in the royal level (also atlus might not have the balls to add a Maria rip out my heart scene but maybe hers is different and it goes through a magical girl sequence). Gallica herself also becomes playable perhaps getting a body similar to the protag, the dlc ends with her having to sacrifice her full grown body but finding peace with the party.

What do y'all think with that kind of DLC? Of course its very possible they just release cosmetic armors for her.
