So, what we really want is your new design (variable slope HPF) plus a 
low pass equivalent (variable slope LPF) and a filter coupler.

Maybe the coupler could be designed with a "spacing" control - a 
frequency CV into the coupler with CV outputs to the LPF and HPF to 
spread the filters in BP mode.  (Along with the continuously variable 
output from LP to BP to HP assuming this is possible.)
