Copy the images verbatim to the smaller disks. Be sure you turn on media perfection to avoid sector relocation difference on a drive-by-drive basis. The easiest way to establish this setup is to install FreeBSD onto a smaller disk with whatever else you want installed to create the initial image, then change the SCSI ID and read the image onto the mastering disk. Then write the image to each new disk. Using vnconfig, you should be able to actually mount, modify, and unmount the image as well to make incremental changes.
