I understand this may be of little if no help, but you can use multi-service clients. For instance, I get all you mentioned covered with Rambox.
It looks nifty but still a server-side solution will be more convenient for everyone, including people using a service's native client. Even with multi-protocol client rooms are not merged and conversations between people across services are not possible thus fragmenting communities since some people will stick to single service, or not use a multi-protocol client.
