The lowest impedence setting on my xovers is 10K ohms. What is the input impedence of the NAIM amps you want to use? If it is a lot lower, I would call Richard and see if he can make filters with that lowest setting at what ever you need. Its possible that 20 percent or so difference may still work OK and at least not void a warranty.
Again, give Richard a call. I have talked to him 3 or 4 times and its been helpful.
