If they don't reuse any of the units from last year, Stars can come up with either Yume x Rola, or Yume x Koharu, or Elza and Rei/Kirara as new units. They have a couple more duos that would be nice to see together (I personally would love a Rola x Mahiru unit) but since the lineup is so strict and they can choose just one I don't see them picking a team that doesn't have a main protagonist as one of the members.
