Neil would be more authoritative about what would differ in the
superblocks, but yes, it is possible to do as you listed above. In
fact, if you create a partitioned array, and your mkinitrd doesn't
restart it as a partitioned array, you'll wonder how to mount your
filesystems since the system will happily start that originally
partitioned array as non partitioned.
