I figure Persona 5 would be an easy Collab since they have with other IPs. Dead or Alive has collabed with Shift Up before in Destiny Child, but since they already have outfits just like Kasumi's, not sure they would do her outfit if the collabed. Ryza has collabed with other IPs recently as well. Genshin is not likely at all, but it still would be cool. Neptunia would be amazing as well, and has collabed before. And the last one, well… ( ͡° ͜ʖ ͡°)
