It should be possible with zpool import.

=46rom the man page:
zpool import [-o mntopts] [-o property=3Dvalue] ... [-d dir | -c
cachefile] [-D] [-f] [-m] [-N] [-R root] [-F [-n]] pool | id [newpool]

         Imports a specific pool. A pool can be identified by its name
         or the numeric identifier. If newpool is specified, the pool
         is imported using the name newpool.  Otherwise, it is imported
         with the same name as its exported name.

Cheers,
Mark
