Renaming the filespaces is an excellent way to achieve this.
As to expiration:  The guiding principal is that if you don't do a
backup of a given filespace name, ADSM won't do any expiration processing
on it...it sits there, as-is, indefinitely.  This is an advantage in your
case, but can be the bane of ADSM administrators, as PC users rename
volumes and/or eliminate file systems such that the previously backed up
data takes up space in ADSM forever thereafter until special action is
taken by the admin.
