If depend of me to pick a concept for the debut of a girlgroup i would use something like this.

And for i could find the guys who make this are kinda cheap. They make a videoclip with the same aesthetic for 150k $ aprox. So is affordable. Ahhh, dreams cost nothing.

Quote from SooYoung

it look like something Aespa could do if SM was trying to give them better quality MV x)

Mmm, yes, i can see that. But the aesthetic is kinda dirty, like inspired in the 80s. But still, i think it could work.
