It can be done on any set that has at least 2 standard type of mixers.

Mixer 1 - used to cancel the output movement - use value of -100% on both ends of stick travel.

Mixer 2 - used to reverse the output travel - use values of -100% on both ends again.

Select both mixers to work from the same switch.

When the switch is off, the travel is normal, when you activate the switch, the travel will be reversed.
