Does anyone have any tips on how to gracefully interpolate between two arbitrary digital biquad filters, possibly of different types? I imagine it should be done in the z-domain, inside the unit circle, but how should the zeros and poles transition between real and complex roots?

Bonus points for being able to smoothly interpolate features such as "cutoff" or "corner" frequencies!
