Has anyone here tried transferring flights in Beijing to a non-connecting international flight without a visum?

I am trying to get a hold of the travel agency to see if I can "connect" a flight to my existing booking, but they are having techincal problems and can't help me at the moment. And I am leaving soon, so I don't know if it will be in time, or if they can help me at all since it's an economy trip with no changes/cancellations.

I don't have time to get a visum and I've read that it should be possible, atleast if I can get an electronic ticket, and then get the ground crew at my departing airport to get my luggage transferred. So now I am going to go for a last ditch effort and order tickets from air chinas website and try to get them electronic and print them out just before I leave if I can't get this fixed in any other way.
