I think the depth issue is an easy fix. It's just injuries are kinda messing things up right now.
After Jade and Bianca split, they end up on separate brands. Preferably Jade on Raw and Bianca on Smackdown. When Becky and Rhea come back, they'll be on Raw unless they want to move Rhea to get her away from Liv.
But when everyone is healthy, I look at the top of each show's roster as:
Raw:
Rhea Ripley
Jade Cargill
Becky Lynch
Liv Morgan
Asuka
Smackdown:
Charlotte
Bayley
Bianca Belair
Tiffany Stratton
Nia Jax
