(DIS)MOUNT/POLICY=MINICOPY.

That is what MINICOPY is for.  (It is groups of 127 blocks, not files, 
which have changed which is the basis.)  I went from 9 hours to a few 
seconds in such cases (slower hardware and smaller disks than you have, 
though, but the improvement should be about the same).

Also consider MINIMERGE for unexpected problems.
