This question is of great interest to me. If, say, I has a 1500 lb
rated caster with a urethane wheel, would it deform under 800 lb

Probably. The easy solution is to use them. Then put some blocks under
the base. That would be better than using just the casters because the
mill would also be more stable than on wheels.
