Michael,
Restoring bits of a backup is not easy and can cause issues if not done correctly.
How many Service Profiles are you trying to restore? If few, it would be faster/safer to just manually re-create them. If many, then I would suggest you download a new logical XML backup, and cut and paste the SP config from your old backup into the recent one, then re-import it with the "Merge" option.
Another option is to use the UCS PowerShell CLI to inject the config. This takes a bit more skill (Knowledge of PowerShell and XML, but is an option.)
Regards,
Robert
