Surely a stereo TRS input on the Crown Will carry the two signals for main LR and monitors separately to left and right

I I use one side of my power amp (Crown XTI) for FOH and the other side for monitors

The main problem here seems to be the mixing of the monitor mix, no issues with the FOH. All can be handled within the mixing app, not with modified cables (or modification to the XR12 ouputs). Here's how I'd do it, based on the provided details earlier (single stereo amp, each side used separately).
Vocal mic(s) : input 1 to 4, set channel(s) to taste, KEEP 'PAN' TO CENTER.
Back tracks : supposing a stereo source, use linked input 5&6 (XR12), set channel to taste, BRING THE 'PAN' BACK TO CENTER (this will create a mono mix of the stereo source).
Mixing app 'MAIN' (FOH) mix page : create desired FOH mix. Use XLR to XLR cable to connect Main Left Out -OR- Main Right Out to one side of amp for FOH speaker(s). Since all is panned center, both have same signal.
Mixing app 'BUS 1' mix page : create desired monitor mix (you can set levels of each mics and back track and even add effects). Using TRS to XLR cable to connect 'Aux1' (TRS on XR12) to other side of power amp for monitor speaker(s). All sources needed for the monitor mix are being controlled from that single 'BUS1' mix page (providing that Bus1 is assigned to Aux1).
Unless I missed something, this should do what is needed.
I have the same request (multiple busses to one output), for a different reason. I'm using an MR12 (Midas version) in a 2-piece MIDI act. We pump all of the instruments through the monitors, but to keep them from swamping the vocals, I prefer to use a bass cut on instruments like drums and bass. That way, we still get enough of the sound to keep aware of what's going on, but the vocal mics stay front and center. So, I would like to make say, Bus1 the straight (vocal) mix; and Bus2 the HPF mix for instruments. The problem is, I still want both mixes going to the same place -- i.e., the vocal monitors.
The only workaround I've found is to use the input matrix to double-link instrument channels:
In1 -> CH1
In2 -> CH2
In3 -> CH3 + CH13
I set CH3, etc. to be flat EQ at normal volume; I set CH13 to HPF EQ at suitable monitor mix. Works great, but it's limited to how many spare channels are left in the board. And it's a bit of a POA, because if I make a level/EQ/etc. change in the 'main' channel, I need to mimic it in the 'monitor' channel. Having a way to feed Bus2 back to Bus1; or to merge Bus1+Bus2 would simplify things.
