It's hard to increase the size of a superblock in UFS without the world going to hell. You'd need a tool for it and there isn't one at this time. Other types of volume spanning include: 1) Device "concatenation" -- what the NetBSD cdd driver does; it could be ported to FreeBSD easily. 2) RAID. 3) Inferior mounts (UNIX uses this last one by default).
