An idea I've been playing with, and as you can see I'm lacking a couple of pieces, but I've got time to tweek it.
I'd like to try PLD GS in Legion when my LS goes to do some runs. I'm not sure how viable it is, but I would hazard a guess that having a GS wielding lummocks who can hit a macro and change to sword/shield might be useful, or at the very least fun.
