Clone emmc for odroid backup

Would it be possible to clone an emmc from one odroid n2+ running HA, insert it in another ordoid n2+ with the original disconnected from network/unplugged? I was thinking this may be easier then using a backup?

Think it can be done from SSH with a dd command.
Haven’t tried it with HA but I have used it to backup my old odroid systems.
