Is this difference actually too big to be using the same R-free set?
If the difference is not too big,  how do I get the reflection file
editor past this error?

Sorry, this has been an item on my to-do list for a while.  The next installer will have options to disable the unit cell (or space group) check (in the "Change symmetry" dialog).  I need to test the new code on something real, so if you're willing to send me (not the list!) the files, I can give you the combined reflections.

There probably are situations where these unit cells are different enough to cause problems (MIR, or switching to new data partway through refinement), but I would definitely want to keep using the same R-free set in this case.

thanks,
Nat
