Should be no problem at all, as long as you torque the lug nuts properly.

Digs up from the brain old engineering calculations from long ago...

Lets assume (for easy calculation) that the weight of the car is 2000lbs, and the weight is distributed 50/50 front to back. That puts 500lbs on each wheel. Now lets add a typical engineer fudge factor of 20%, which gets us to 600lbs per wheel. Divide by 4 lugs per stand, and you are putting approximately 150lbs of shear force on each lug.

Now, consider that even without the hub support, with a properly torqued lug, roughly (from a calculation I recall long ago) 80% of the shear force when static, is taken by the friction between the hub surface and wheel surface, and only 20% is taken by the lugs. Lets be conservative again, and say that it is 60/40 instead of 80/20.. thus 40% of that 150lbs is taken by each lug, or 60lbs of shear force per lug.

The cross sectional area of a lug is about 0.175 in^2, thus the lug experiences a shear of 342psi. The shear strength of an SAE80 steel lug is in the neighborhood of 90000 psi (150000psi tensile strength * 60%)

342psi is much smaller than the 90000psi strength.. so.. you should be OK

Edit: feel free to rip this calculation to shreds..
