I don't think paralleling the filters will impact the nominal input
impedance of each filter.
If you have a SA and have something to generate a 45Mhz signal you
could sweep the filters in parallel and see what it does.

I rolled the dice on a pair of filters and received Toyocom 45E1A9Fs

as
two pole filters at 1200 ohm termination impedance. If I parallel
those will I bring that impedance down to 600 and should that be a
goal? Should I try both in parallel? I do have a modest spectrum
analyzer to take a look at the results with.
