Perhaps this should be possible? If nothing else, it should technically be possible to hook it to a load and run the odometer up to what it should be. You'd have to be careful not to overshoot, since you can't reduce the value on an odometer if they're properly designed.
It'd still be useful to denote "this vehicle has had the odometer replaced, but care was taken to ensure the odometer value is within +/- 1% of the authentic value"
Of course, this is really only for mechanical-style odometers. Digital ones, I know almost nothing about, wouldn't surprise me if there is no "stored mileage" in such an odometer.
