PLLXO question related to LDR

Been wanting to try one of the new light dependent resistor attenuators as a passive pre in my system, to replace the old Channel Island jobber I use now. The recommended system requirement specs for this design is a source of around 200 ohms output impedance and a power amp of 47k ohms or more input impedance.

I'm good with the output impedance spec, will be using a Dodd tube buffer after my DAC, utilizing a 6H30DR which will give me about a 100 ohm output. Power amp wise my Aragon(s) are low, 22k ohms, although folks have used amps with this low of input impedance and reported success. I was wondering, can a passive line level crossover be designed with a high input impedance, say 100K ohms? That way I can take care of two issues at once.
