I've done that. I had a workpiece that had three non-colinear tooling balls which were accessible in both positions. I used my actuals from the balls in the first position as my nominals for the second position. At the beginning of the 2nd position inspection, I found it helpful to level or rotate to a generic line whose K nominal was 1 and K actual was -1. Been a few years since I did that, and there are probably better or easier ways to do it, what with all the smart guys on here. But my point is it is do-able.
