Yes. This can be done even with a basic K4, since it has independent left and right receive channels pertaining to VFO A (main) and B (sub). 

A K4D would give you the ability to use different antennas for the two receivers. It also optimizes performance when the two receivers are on different bands since it includes a second set of band-pass filters, preamps, and attenuators.
