Replace Menja: Shiho- Shiho is altogether too non-white to be a perfect replacement for Menja, but she could be turned into a defector from the ABB that joined the Chosen. After all, there is a precedent for particularly useful Asians to be seen as Honorary Aryans. She would also gain a power set on par with that held by Menja
Replace Menja: Piura- a much larger rework would be needed to make this work, but we can make it work. Hmm. Svartalf, a case 53 with earth control powers, could be retconned in as a former member of Empire 88 in place of Menja?
Replace Ireena: Shiho: SYNERGY BONUS UNLOCKED- For some reason, this card seems to resonate more strongly with the role of an attractive young woman being victimized by a horny older man. Using this combo will drag along more baggage from Shiho’s original setting of Persona 5, taking the form of a group of adventurers based on the few Phantom Thieves that ever interacted with Shiho. 2 guys, 2 girls.
Replace Ireena: piura: Ok this one would be funny. Having Strahd Von Zarovich trying desperately to seduce a sapient mole man would be neat. The recast item allows Gil to be selective, so what this would do is completely throw the scent off Ireena while preserving her relationship with Ismark, for example.
Replace Rose: Piura: We could also have the case 53 mole man sub in for Rose, allowing her to shed all of Flechette’s responsibilities. Might be better to wait to do this until we want to fully extract her, or until she has established some relationships outside the Wards.
Replace Rose: Shiho: Synergy unlocked: Replacing an athletic Asian girl with an athletic Asian girl Is less of a stretch, and will thus carry more baggage from Persona into her life. This will likely take the form of at least one new cape on the scene in Brockton, in the form of her best friend Ann.
Replace Keilnei: Shiho- it would be a hard pill to swallow, but if we wanted to keep her around this would be the most brutally direct method.
Replace Keilnei: Piura- Same
Replace Noa: Send forth Shiho to be the new Terra caddy, with the full training and combat ability that Noa’s upbringing provided.
Replace Terra: Piura is othetwise useless. Turn them into a new Ra-Seru or something similar do defend the world on a budget
Save them for something later, knowing what they are capable of.
