Note the order of the partitions is not important, at least on paper anyhow. Of course there are preferences in sense that it does look nice if freebsd-boot is in front. Also, if you do have mirror setup, it is some work, but you can re-arrange mirror side partitioning (with usual cautions like having scrub done, having backup, having third disk would be helpful).
