Does anyone still remember this one? They used to be part of Jim Lee's WildStorm Universe, under IMAGE Comics. Then they went under DC Comics. Original GEN13 artist J. Scott Campbell's art is semi-inspired by anime anyway, so a Bishoujo line shouldn't be a tough sell!
Caitlin Fairchild, Rainmaker, Freefall, and Bliss would make AWESOME Bishoujos!
