I have come up with my own solution to this.

As I'm not worried about distortion I simply use a passive adder circuit which adds 3V to a ±2V signal. This can be switched using conventional, ground referenced circuits. Then, when I want to output it, I pass it through a capacitor + emitter follower amplifier.

The biasing adds some DC to the AC, muxes it appropriately (not shown), then amplifies it and converts it back to AC
