You are correct; there's no way to "spoof" TSM this way.

About the best you could do is either export the node (or run a
backupset of it), delete the node's filesystems, and start over with
fresh backups. After a sufficient amount of time (at least a couple of
months), you can ditch the tape(s) with a DELETE VOLH T=EXPORT (or
DELETE BACKUPSET).

Keep in mind also that if you run SKIPNTPERMISSIONS, and you have to
rebuild the box later, you'll have to change all of those permissions
settings again.
