I think the question deciding the quality of the filter fade is, how
big will the phase difference between the two filters be? Amplitude
differences shouldn't matter when we crossfade, as long as we're not
phase-canceling.

These are very simple filters that don't take long to settle on a
stable phase relationship. A reasonably small parameter change will
not change their phase response by much, so my expectation is that
there will be only little cancellation and the fade thus close to
imperceptible; at most a slight attenuation of high-frequency content.
Just theorising over a glass of wine though.

Yes, that is a very convenient way to solve it, perhaps the preferable
one given the realities.
