Did you try a prybar against 2 of the studs to lock the hub so you can unscrew a wheel stud? Kind of like turning a motor on an engine stand when there isn't a crank bolt in it; screw in a couple of flywheel bolts and use a prybar between them to turn the crank. On in this case you use 2 wheel studs that are side by side and a prybar to keep the hub from rotating.
But maybe I am misunderstanding something. Just an idea.
It's a worthy idea. I did something similar where I "locked" up two wheel bolts against each other on the same bolt so that i could get a wrench on one and hold the hub in place. No dice though. The torque required to unscrew the studs was too great
