My opinion: If a competent operator, on a machine that isn't junk, can't grind .001 off, I'd look for another shop; at the very least polish it off......it can be done
If you’re lucky enough to have a crank grinder that is less than half worn out, and an operation that can work with taking .0005 off a side, and assuming it’s the same machine and the offset is exactly the same...then yes, you can do it.
