It might be that "exiftool" already has the functionality needed - quote from the man page:

exiftool '-FileModifyDate<DateTimeOriginal' dir
Use the original date from the meta information to set the same file's filesystem modification
date for all images in a directory.

A problem with unconstrained exiftool is that to be safe it makes a copy of each file it modifies, so there's generally a lot of cleaning up to do after running it.
