I don't think there's a way. I did a competitive evaluation of ADSM vs
Harbor, a mainframe-based storage manager.
Harbor did have the nice feature that it could make a copy tape on the fly.
But I looked hard for a way to do that in ADSM, and at the time, there was
none. (Though using a disk storage pool gets you similar functionality,
i.e., you don't have to back the client up twice to get your copy...)

I've actually wondered about this. I've been told that in the mainframe
world, they are able to make two copies of the same file at the same time,
i.e., mount two tapes, and stream the file off of disk to both tape drives.
I'm told this incurs quite a bit less than the 2x overhead you would
normally expect from making two copies. Does anybody know of a way to get
ADSM (or even just AIX) to do that?

Did you at all consider COPYPOOLs? Or are you unaware of them?
Copypools were made for DR. Just setup a rotational plan to send
tapes out as the fill up and reclam on weekends all the ones that get too
fragemented during the week.
Call me if you liked to here what we do.
On the other hand if you need something more 'archival' in nature then use
backupsets.
or both if you need both!
