You already have a variant of this at https://keyserver.pgp.com
(although I don't recall if they send the requests encrypted, I
haven't looked into the service in years)
In general I believe this to be an insufficient form of identification
that really doesn't provide much of anything useful, but at least the
PGP keyserver does it reasonably sane in its methodology by creating a
signature from their CA on the key. Whether you put any merit to
having such a CA signature or not is left up to the user (excluding
for now the "fun" related to the spammy number of signatures from it)
