Yes, but why don't mount the ISO at the host system and do a nullfs mount into the jail?

at the host system (not in the jail)
# mdconfig -a -t vnode -u 10 -f ${path_to_iso_image}
# mount_cd9660 -o ro /dev/md10 /mnt/
# mount_nullfs /mnt ${path_to_jail}/mnt

ssh into the jail
# pkg_add /mnt/filename
