hi Mark,
ok,
actually the problem is we have no idea of what
the circuitry looks like around that mute knob.

Maybe it's worth phoning your local Behringer dealer
and asking for a service sheet. It's not an unreasonable
request.

I had a look at the manual for the mixer, it doesn't have
a block diagram.

If the inputs were mono
making the Mute button hack on *one* channel would likely
have an effect on the signal that's going through the channel.
i.e. you dry signal might drop in level.
...it's *possible* it would work ok of course,
  but I'd be surprised.

Doing it more than one channel certain to produce problems,
...the channels with the "mute" button presses would all be shorted
together...each of those tracks would have the same blend of
inputs going through it.

..and as your using stereo, there's no option to just use
one channel at a time.
(any stereo ch you used the mute button on would be
  mono-ised)

That's why there'd have to be, at minimum, some resistors on
each connection from mute switch to the new "bus".
(which would need some additional gain to compensate).
