Yeah, the max possible rate is the issue with standard hardware. It becomes more of a problem with wings and banking added to the equation.

You're not absolutely could grind the effective diameter to get rates in between what's commercially available. It's just not really necessary...a 0.025" diameter change is usually less than 25 lb/in difference in wheel rate, depending on geometry, so it would be a really small effect for the amount of effort involved.
