TelePost Inc (i.e. N8LP) provides such an add-on. It's called LP-Pan.
If you're suggesting that Elecraft should provide an internal module
option for this... I suppose that might be technically feasible, but
I'm not sure it'd really be much of a value-add, since LP-Pan works
well.
BTW, from what I understand, the KX3 architecture is quite different
from the K3, and it actually uses I/Q internally, so it's "easy" to
make the I/Q signals available externally, whereas the K3 requires a
converter (like LP-Pan) that takes the IF as its input.
