Analog multiplexers work fine for dorect conversion receivers, so you could just take the audio from the mixer output. Sadly that gives you audio from both sidebands. If you mix in some passives or actives a Phasing receiver could be built to do away with the unwanted sideband. Or maybe one could use the Weaver method for ssb demodulation. But Weaver has it's problems with the switching frequency breaking thru. But that's less of a problem on receive.
