No, that will not give any benefit. The UAC cannot respond to a challenge using any particular algorithm unless it has received a WWW-Authenticate/Proxy-Authenticate header (challenge) for that algorithm, because that header includes information (nonce, etc.) needed to provide a valid Authorization header using that algorithm. That is why the device challenging a request must provide WWW-Authenticate/Proxy-Authenticate headers for all algorithms (and domains) for which it will accept Authorization/Proxy-Authorization headers.
