Vegapunk Siblings

Yes, it's only these three. It could be an AU where all six are siblings where the sisters (assuming they're 'shes') are streamers with their brothers either doing technical support or their own things. The girls stream their interests with the shared handle, DrVegaBabes:

York is the oldest sister: tranquil, empathetic model and a taste-tester, too.
Lilith is the middle sister: stealthy and mischievous prank master.
Atlas is the youngest sister: Short-tempered junior MMA fighter.

BONUS:
Nicknames they like - Yor (York loves Yor from SpyXFamily), Lily and Atla
Nicknames they hate - Yo-yo, Yorkie, Lil, Lil Sh*t, Attie and Lassie (she's poofy like Lassie and as vicious as a feral dog. Also, I thought of 'Las'sie because of the last three letters of her name: At'las'.)
