Why not do it the other way around? Create a pool which consists of mirrored pairs (or triples) of drives. You don't need raidz to make it appear that the pool is bigger and it will use disks in the pool appropriately. If you want to have more copies of data, set copies=2 and zfs will try to schedule writes across different mirrored pairs.
