You'd need to create a failed RAID1 array on the other disk, create partitions (probably best to use LVM on top of RAID1) on that, then clear the new disk, mark it as RAID1 and add it to the failed RAID1 array, wait for it to sync up, mark the new disk as failed, and shutdown and remove the disk...
