It still wouldn't hurt to ask. I have talked with them at the
Huntsville Hamfest, and they are very knowledgeable. They might have
an idea, or know of a product which will do what you want.

Tks,

I also had a good look at the circuit and the only way seems to be to
"hack" the pc board that my Inrad xtal filter is connected to, so that
a second filter may be switched with micro c/o reed relays, possibly
at the cost of some signal leakage.
