I tried something like this - I used rsync to replicate the SD card's (mounted) msdos partition onto the SSD's (also mounted) efi partition.  That got past the firmware message, but then it stopped in the boot loader asking for a partition to boot from.  'zfs:zroot/ROOT/default' resulted in an unknown partition.

At the moment, I'm running with the SSD imaged from the FreeBSD RPI .img file, and that is working, but it's UFS, not ZFS.  I'll give your steps a try, and if I get nowhere, I might wind up creating a UFS partition for root and boot, and make the rest of the disk zfs with my desired filesystems.
