Honestly, I don't believe you could remove too many bass. In your case, I would probably remove every single one shocked up, especially those with low Wr. Wr stands for relative weight.
I would also remove any crappie that came up as well. I think you will still leave plenty of bass to continue to keep pressure on your BCP and BG to continue growing quality panfish. The removal of the bass may also lead to slightly better bass growth. You could also look into stocking some HSB to fill out the missing biomass with the bass being removed. The HSB would be a great bonus fish for your fishery and also help control crappie reproduction...
Just my two cents...
