If there is a Queendom, will Brave Girls be too popular to qualify?

Maybe they can appear as a guest for someone else's stage.

IMAGINE ANOTHER 2ND GEN GROUP COMING BACK FOR A CHANCE TO SHINE AND BRAVE GIRLS GUESTS WITH THEM. (aka can we have a 9 Muses comeback but without the shitty CEO)

but again Queendom is for popular girlgroup just like MAMAMOO , IDLE and AOA on 2019

why not?

If there is a Queendom ?? There already has been one

Mamamoo took part in it. For a fact they most probably want popular groups .
