Not overkill at all, Phil, if you are into CW contesting. Especially
something like the 160 meter events.
But I would recommend the 200 Hz 5 pole rather than the 250 Hz 8 pole. The
250 and 400 are actually pretty close in actual BW (see measured data
available elsewhere). I use the 200 and 400
G'morning, Phil:
After taking a look at the response curves for the filters, I chose the
5 pole 200 Hz filter to accompany the 8 pole 400 Hz filter. I find it
useful in the crowded bands during the contests.

Ditto. W4TV (?) measured the 250 (actually 370 Hz) versus the 200 and the
latter had more rejection at ALL frequencies, even though it's only a
5-pole. I only use my 200 ~1% of the time (500 Hz
and 200 Hz filters.

Phil,
Don't get so stressed. My K3 has 3 open filter slots, and it does not
concern me at all.
How much serious contesting do you do - how much serious DX Chasing?
Consider my logic: The DSP filtering alone is really good and will
handle conditions under more casual situations than the above.
