Connecting to Google Chat from Google Talk, possible?

Hello, I recently learned that there is another messenger in Google, which is developing, Chat. And as far as I understood he is the heir to Hangouts and Talk. I had this idea, I do not have a truth in any way, because I have no knowledge, but whether it is possible to theoretically patch Google Talk, to work with Google Chat?

Google Talk servers are gone now, and use different protocols.
Don’t think its possible, but what Google Talk client are you referring to?

I mean official. Well, I’ll tell you how it is, I have an old PC with Windows Vista, and in this case, for the purpose of supporting the time period of 2007, just for interest, etc. But even if it were to be used like that, it barely drags the web. I just read that when Google Talk was turned off, it was possible to connect to Hangouts. Hmmm, maybe it’s a proxy, maybe it could be patched and something would happen.

Google Talk unfortunately isn’t similar to the new Google Chat, so I don’t think it’ll work.
