because there's characters like elza whose full names are already given in western order. it just makes for consistency, and even within the series when idols are performing, their names are shown in western order on the screen.

i believe in terms of singers, it'll probably work out the same way it did during the switch to akari generation with ruka and mona. sena and rie will be part of a new group (most likely named "aikatsu friends" as well), but will take a bit of a backseat while new singers take the lead. the other aikatsu stars members have too many characters on their plate already.
