Why not use backupsets? I know, you need 1 tape per server for each
backupset as opposed to putting all the new monthly backup data in its own
pool and filling the tapes.

We thought about a couple other ways around this...virtual volumes to
another server and having a FILE device class for the backupsets and then
archiving the backupset files to TSM tape.

For the virtual volumes, you need another TSM server license and full
support for backupsets as virtual volumes is not there. The RECONCILE
VOLUMES command does not recognize a backupset as a valid volume type and
deletes the virtual volume, but not the related backupset entries. It works,
but you have to remember to NOT run the command.

For the FILE devclass, you need enough disk space to hold a backupset. Plus
to restore from the backupset, you would need to retrieve the archive that
contains that backupsets' files first.

Just some $.02 worth...
