I think David has hit upon the crux of the matter with the tag line in his sig: "There is no pillow so soft as a clear conscience." Will you be able to tell the difference in actual single-receiver operation between the 2.7 kHz 5-pole and the 2.8 kHz 8-pole filters? Almost certainly not. But will it make you feel more comfortable, knowing you have the better 8-pole filter in all slots? Undoubtedly, based on reading between your lines! Is it worth the cost differential? For you, sure, probably.
If and when I decide to buy the KRX3, I plan on replacing the 5-pole 2.7 kHz filter in my main K3 with the 8-pole 2.8 kHz, along with an 8-pole in the added KRX3. In the meantime, I'm finding the 5-pole filter works very adequately. (I already have the 8-pole 1.8 kHz filter installed for narrow SSB work, however, which works great in crowded bands.)
