Default Can this circuit using B1 buffers be simplified

I am redesigning my prototype cross over using B1 buffers and i want to add baffle step control. In the picture you can see the circuit i have in mind. The prototype already uses the 2nd/4th order filter + volume control. But i would like to simplify this circuit.
- Can i avoid putting the filter caps/resistors to ground and could i put these caps/resistors between the hot and cold signal line?
- Can i avoid a reference to ground at all?

More information:
- the BSC can be switched of by a shorting switch , this is not indicated in the circuit. With this i shorten the BSC and a B1 buffer
- filter slope (2nd or 4th order) is selectable by a switch. I have 2nd or 4th because the setup is balanced.
