Don't count on it. The filter offsets *are* matched for all
8-pole (250, 500, 1000, 1800, 2100, 2800, 6000, 13000 Hz) filters.
When using a receive bandwidth greater than 2800 Hz in SSB, it is
not a matter of matching the offsets between the 6 and 2.8 KHz
filters. Using different filters violates the principle of diversity
reception - the *carrier frequencies* are different (which is not
possible due to the use of the same oscillators for both receivers)
because the filter skirts are different distances from the nominal
filter center frequencies.

Over on Nabble is where this discussion got the most interesting.
Based on this last post from Wayne ...
If the filter offsets aren't matched, in diversity mode, the firmware has to
set up the main/sub synths differently rather than drive both receivers from
the main synth. This is supposed to be working, but there could be edge
cases not covered yet. I'm looking into that.
