you can do system transfers between emuNANDS, yes
but they won't be the same, they will still be 2 different emuNANDS, even if the only difference is the encryption key
however, someone should note, that if the intention is to copy eshop games like this via a system transfer, yes it is possible, but the emuNAND, which is just the injected backup, can't (or shouldn't) go to eshop anymore, because it will check the download tickets, see they are invalid, and then delete them, because the tickets got transfered to the other emuNAND
