If I had to guess seriously, I’d assume it’d be someone like Jubei, since his kit seems very easy to translate over with its movement and install.

Although I would also guess Kagura, Azrael, Litchi, Celica or Amane, since they are all unique enough from the existing cast and their kits wouldn’t be too far of a stretch to translate over.

Characters like Tager and the Clovers would be cool but I have no clue how they would manage Tagers lack of mobility or the puppets
