No!  It would not be nice - unless you like shooting yourself in the foot.
Anything that lets you alter a backup destroys the integrity of the backup.
Think of your auditors - if they understood how good tsm is, this command
would destroy all their confidence.

If you have gone to the trouble of collocating the primary pool with move 
nodedata
commands, you can collocate the offsite pool by defining a new copypool and 
backing up to
it.  After the new pool is all offsite, delete the volumes in the old copypool 
with 'discarddata=yes'.

I really hope this helps,
