Bob-
It is unlikely that you created an "out of round" condition on the crank
given the relatively short time frame it ran until discovered. I would think
that as long as the woodruff key slot in the crank was not damaged too
badly, that you should be fine using a different balancer. If there is some
excessive tolerance on the woodruff key fit, then you may need to shim the
woodruff key or make a date with your machine shop.
If you have a dial indicator, that should verify and out of round condition,
it could also help in verifying the radial slop in the woodruff key as well.
