You'll have to get crafty since you're not pulling the trans out and doing this "properly". Carefully and fully unstake the nuts before blasting them off, that's a given regardless. For torquing, you can try a wood wedge into the gears, or an aluminum/brass wedge would likely hold up better. Engaging a gear and having someone hold the brakes tight might be enough, but we're talking about 195 lb/ft on the big 50mm nut..... I guess my answer is whatever way you find to make it happen, with the least possible stress on the bearings or gear teeth.
