I'm not sure of what they are ultimately wanting, but 
without using HSM you could do as you described.  Then 
I would run bpduplicate to duplicate those images on 
disk to a tape storage unit (which I'm fairly certain 
you can do).  If the disk is only to be used 
temporarily, then you'd want to expires those imags on 
disk after the duplication and then change the new 
primary copy to 2 for restoration purposes.

With HSM,  you could use it to migrate those images 
stored on the Disk storage unit to tape.  the only 
problem there is for restores.  You'd have to demigrate 
then do the restore.  Whereas in the first example your 
restores would come right from tape.

just a thought.
