The goal is extreme precision, not speed persay.
Then the obvious is to slow things down and get the steppers back into their "comfort range" as you put it.
If you use steppers, then you are already confined to this. If you want some redundancy, you could use the step verification within Mach3.
Extreme precision is not achieved by what you suggest. If you want true closed loop, get true closed loop! Don't use a band-aid.
There is nothing inherently wrong with a stepper motor system when designed correctly. You just need to stay within the capabilities of that system. If you are loosing steps, then by definition, you are exceeding the capabilities of the system.
