Good thinking.
Sure a lot easier than unbolting the blade and moving it over (like mine)
I did do a "upgrade" that you may be interested in. Across the backside of the blade in the middle of the curve, I added a piece of heavy angle. I think it was 1 1/2" by 3/16 --> didn't have any 2"by 1/4 or I would have used that. It really stiffens up the blade to keep it from bending when a rock, root or stump is found. There is also a 2' long 1" rod welded vertically in the back to stack weight lifting discs to give it the heft it needs to really engage the ground. Works as a handy handle when getting off and manually spinning it around in the snow too!
