Does it work with sites like Google from Google Chrome where browser knows about their public keys? I think that this will be wide practice in modern browsers.

HSTS/HPKP headers could be stripped by proxy but preloaded public key list probably will require custom browser build.

Yes, it does. Google intentionally adds exceptions from error reporting in the case a root CA was added to the OS.
