Yeah, he can use the script to find orphans or--my recommendation--just 
put the "interim" shows in MythVideo instead of MythTV.

Using a partial restore to "merge" 2 different databases will fail.

/me really needs to put that orphaned metadata and orphaned file 
handling in mythbackend where it belongs so we can delete the legacy, 
unmaintained scripts that try to handle it (and generally do bad things).
