I can't think how. The MITM can as easily change that public key to its 
own one and use the original itself as the client could use it in the 
first place. Security 101 - never send the vital key data over a suspect 
channel which relys on that key for protection.

The whole of this thread is beyond WG charter IMHO. Let us stop circling 
the drain on it.
