Break the mirrors and then you have a free drive. Setup the pool how you want on this then rsync all your os build over onto it. Make any zfs root tweaks you want then boot onto the drive. If all is good then copy across the partition table from the zfs drive to the new one (gpart backup/restore) and attach the relevent slice/partition to pool. Finally put the boot blocks onto the drive, job done no work lost
