So basically I could set the compensation value exactly the same for both
filters and accept the difference in passband frequency response... whatever
effect that will produce.

I agree will Bill W4ZV, it will be interesting to play around with
diversity. I can already visualize another coax from a second RX antenna
entering the building. I though I had that figured out last season with the
new antenna switch... the game never ends :)
