With how the society today and how many pick me girl who refused to be associated with that kind of concept, I don't think it will well received and being as popular as before even many begging for big company to produce that kind of group again. I mean not only pick me girl but girl crush concept honestly more interesting especially for the group storyline. There's a reason why girl crush become more and more oversaturated, because it brings more audiences today than group that doing the cute concept. Female fans attracted to strong, badass women concept in line with the women empowerment. And in kpop, women's buying power is bigger. Obviously company seeing this through and gg started to targeting female interest that male. See how gg with girl crush concept today having more female fans and it translated well in their sales that becomes more like bg.
I can see other concept like GFriend or izone become more popular than girl crush, but never the cute concept.
