The junior thundersticks, although maybe smaller than what you want to present,  that you referred to in the original post work well with the bottom bouncer set up. Just make sure you have enough leader back to the lure. Also using a three way swivel with lighter test mono on the dropper to a bell sinker would work. Given your understandable concern of keeping as many cranks as possible from the rock bass that inhabit all of the likely fishing spots, the drop sinker is a small price to pay. Just another option.
