That's unlikely to work, because malicious people can publish anything that legitimate lists can. There's a fundamental rule that anything you publish about yourself can only decrease other people's opinion of mail that appears to be from you, not increase it. DMARC, for example, is all about saying mail that appears to be from you actually isn't.
