Hi Luis:
We have used the same results from a measurement system study for other areas, as long as we determined that the methodology was the same. Likewise, we have used one 0-6" caliper and applied the results to other areas that use 0-6" calipers, wven if they are not the exact same calipers.
You should be careful when determining when to do this. If you have 8 stations and 8 sets of identical measurement devices, measuring like features, you could decide to only use a couple of these for the R&R determination.
Also, the actual R&R result - the actual error, not the % of tolerance result - could be applied to another tolerance on another part, again if the measurement ssytem is similar enough.
