Dear km6z .
The (Professional) suggestions you offer are correct and about the same of what I suggested at the beginning, although I expected a somewhat simple PA mixer.

No doubt because of your former Pro Sound and Recording experience, you fly much higher:
Problem is, there are NO "multiplexer/line reversals/direct channel outs/out returns and sends/subgroups/aux busses" .
Nothing at all.
Not even a regular conventional mixer nor a simple Powered Mixer Box.
And no Board Operator either.
Ugh !!
From what I see, that Bose system is a *very VERY* simplified PA amplifier, only 2 mic channels, probably 1 XLR and 1 Line in , period.
What looks like a speaker stand is the actual speaker cabinet and power amp.
The cellphone sized box in its middle is the Mixer.
The two shoeboxes to the right are the Subwoofers.

Thatīs why I find to that to comply exactly with what the OP asks, everything must be "outside".
The system I suggest includes whatīs necessary: 2 XLR inputs, some amplification to turn audio into unbalanced line level signal to simplify everything, channel send/returns to interface the Harmonizer, multiplexing to assign it to the desired channel, and outputs suitable to plug this into the Mixer.
Simplest/cheapest is to exit as a line level signal but if necessary XLR can be available too.
A 3 button pedal would also be necessary: A/B/none
As a side note, I can roughly design such a system in a couple days and test/polish it plus design a PCB, front panel, suitable cabinet, etc. as needed to produce a working prototype in, say, 10 days, but itīs impossible for a single unit (or a couple).
Iīm sure you and many others around here can do the same.
If there were possibilities to make and sell, say, 200 or 1000 of them, the effort is worth it.
But I doubt such a Market exists.
And as I said, to make just one itīs *way* more expensive than buying another Harmonizer and just switching them in/out as needed.
Oh well.
I'm sure that if we were in China, rough ideas such as this would be in US (and rest of the World) dealerīs shelves in a month or two.
Oh well 2.

I'd rather plug them straight into the proper mixer channels and switch channel effect assign jacks *or* have the PA operator add the effect to the proper channel when necessary
a multiplexer handles the line reversals just fine with a very simple logic steering, one control line. It is certainly doable, and even trivial if there are direct channel outs, or if more than one aux returns and sends, either way, and without having to remember which mic is in hand at any given moment.
The question was how to do it with a circuit. Answers were given that are relevant. But the problem is probably not best solved...if it IS a problem, by hardware changes. A competent mixer with subgroups, clickless muting, maybe with direct outs or some spare aux buses can already do what is requested.
Unfortunately little is known about the features of the gear being used, there is a good chance if there are free subgroups or auxs, nothing more than a mute button is needed to be pressed to switch the effect to the opposite mic. Overall, however, it seems like a poor way of handing stage craft, when hardware sets up a less than conventional use of the signal paths are hard wired it limits at least one channel to a range of use. A better solution probably involves figuring out why the OP thinks this is a performance solution at all. What is being asked of the gear is something that normally would be handled by the board operator without any hardware.
