That's an interesting idea, it seems GnuPG has some support for sending keys via
e-mail.
From the "--keyserver" option documentation [0]:

I didn't manage to get it running though ("gpg: keyserver send failed: No
keyserver available"), probably it depends on some package that I don't have
locally.
By the way validation of keys sent from e-mail would require DKIM as it's easy
to spoof "From" (that's why most solutions send verification e-mails to the
e-mail address instead of receiving it).
Kind regards,
