For my tool i don't really think that's possible as of now, through OSC you don't get the audio signal (afaik), maximum the level at some precision.
Also general audio stuff is from 20-20khz, so you don't really have headroom to super(or sub?) impose another signal into it frequency wise, as it would be audible. (Unless you sacrifice some parts with a high/low cut on the original signal.)
Although you could have 48khz sampling rate on most audio gear, so you could do time-multiplexing if you are really desperate, but then all signals need processing before becoming useful/noiseless.
About the cable sheath, of course you can do anything with custom circuits, but general audio stuff will not help you in that as far as i know.
If you ask it because of controlling the cam with a mute status felt out-of-place for you, then: no it's not wasting any channels. As someone above already explained very precisely above, the thing is you don't want to have live and unused microphones on your setup, due to feedback, extra noise, etc.
So if the speaker is speaking, the band is muted, if the band is playing the speaker is muted. And this can be used (in our case, not always for everyone), to track where the event is happening, and the camera can turn at the right position based on this. Therefore we, in our usecase could eliminate an extra step for someone to manage the camera by hand.
By the way, many consoles have extra buttons/knobs that are assignable to random stuff, so through OSC i could query their states as well and i could set up camera movement with those as well if i wanted to.
