Hmm... what if instead of a new cast every season, the Inner senshi did die as Naoko intended them to in the first arc ....and we'd get a new set every season afterwards? For example, R/BM could've had Chibiusa and Pluto as Sailors, S/Infinity Pluto, Uranus, Saturn and Neptune, SuperS/Dream having the Quartet and Stars having a larger focus in traveling to planets and also meeting their senshi + Galaxia's minions?
