The issue with removing the blade isn't needing to keep the blade from spinning when removing the nut, or using an impact gun. Ihave an impact gun, and honestly the nut isn't on very tight. It's loose enough that the blade spins freely on the spindle, but the broken spindle is also spinning and there isn't enough friction on the spindle for the im pact gun to actually remove the nut. Additionally because of the extra pieces on the spindle and grease cup there isn't any place on the lower spindle that I can put a clamp or wedge anything in to get enough leverage to let the impact gun do it's thing. I need a way to stabilize the spindle shaft.... hence my elaborate plan as described above. Will see how it goes in a week or so.
