Bouncy Rear Suspension on Air Cups + Helper Springs

I’m in a bit of a pickle. I’m on 30k springs front + 6k assist springs and 24k springs rear + 4k assist springs. Was previously on Stanceparts Air Cups and upgraded to HybridAir Bags for more lift a year ago. (Pics are from when the car used to be on 18k springs, still rubbing on the wheel wells when hitting dips)

Something I could never solve was the bouncy rear end. In order to get enough lift I sagged the spring perches and took up the slack with assist springs. When the car was still on air cups the rear was actually a helper spring and the front was just free-floating with no helper/assist bouncing around like a skateboard.

I got custom valved shocks built to 28k effectively underdamping the front and overdamping the rear. Short of removing the rear assist springs and properly preloading the 24k main spring…. is there any way to solve the bounciness without loosing the suspension travel needed to air up over obstacles?
