Not really.
You can use SSH forwarding of the connection, and use the public key
authentication for that one.
Or you can use Kerberos 5 - while not public key authentication, it may
accomplish what you wanted.
You can also request that the client has a client certificate on a SSL
connection, but you cannot map client certificates to user account so
anybody who has a valid client cert by your CA can connect then.
