Wouldn't that cause metadata in previous custom columns to disappear, if the random db doesn’t have the exact same custom columns as what was stored in the opf-files?
It could be a good idea to test it, but make sure to have a backup of the corrupt library, if it seems that a complete restore of all metadata fails.
It assume it should be possible to examine a opf-file to find out what custom columns was used when the opf-file was created?
