Personally, I'd just use rsync to back up the contents of sda rather than doing a dd of the whole disk. That way everyone could have their own UUIDs.

If I understand correctly, doing rsync backup would not guarantee this direct boot functionality.
Actually, with UEFI you _can_ use rsync and preserve the boot function. The old days of boot code depending on absolute disk block addresses are gone. All stages of the boot loader now parse the file system structures to locate the blocks to read, so there is no problem with files not located at the same physical addresses on your two disks. The EFI partition is required to be an FAT filesystem because that's what the UEFI firmware is able to parse.
