lol no

You seem to not have thought this through very well. I mean, there are so many questions that would have to be addressed if this were to work.

Which site's rules would the new chat fall under? Do we really want fascist rules from VoA and GATB taking things over!?

What about banned members? I am banned from VoA and GATB, and I allowed myself to get banned after I saw how fascist they are. But the point is... which bans from which sites would apply to the new chat?!

I think you're inadvertently opening a can of worms here, and also, creating a slippery slope.
