I just think that sudo will use $HOME as /root so one way could be to
provide HOME as your own one.

maybe like this:

export SUDO_EDITOR="env HOME=/home/myusername EDITOR"

but if you are using emacsclient that implies you wish to have server
running, so in that case server has to be started. As I have started
server as me, as user, this works just fine:

export SUDO_EDITOR="emacsclient -t -a ''"

on my side.

And this works as well good:

export SUDO_EDITOR="emacs -nw"

But if I would be user joe who wish to user HOME configuration of user
john, then I would be doing something like:

export SUDO_EDITOR="env HOME=/home/john emacs -nw"

provided that configuration is readable.
