Congrats on the new ride!
My 2018 XT set-up is:
SW Motech Crash Bars
OEM Center Stand
Happy Trails Skid Plate
and they all work well together.
I had some trouble getting the HT front bracket mounted to the SW-M cross bar... the holes in the bracket did not line up at all with the SW-M screws. It looks like SW-M might have changed the way the cross-bar connects (the HT instructions show the old-style SW-M cross bar I remember from my 2005 setup).
I drilled a couple of new holes into the bracket to line up with the SW-M screws and that worked.
This is how the "new" SW-M setup looks...
