I just experimented some W/D/W system similar to what I was using before.. The KPA can be set up for this but it's en hidden function 
First I got the monitor out carrying ONLY the signal up to the stack output ..not more..sent into the Matrix module and into a Port city 2 x12.Cab off on monitor out ..this carries only a dry signal as the output is taken just before the post effects ..if you're using an FRFR you can just leave the cab ON
Then two active FRFR from the XLR outputs..there you can send either some full wet or mix a bit of dry
It sounds really big 
If you want to experiment with this you'd have to ask Christoph how to select stack out instead of main mono out at your monitor output .............
