Is it possible to disconnect a running x-client from one x-server and connect it to another?

I'm running an x-server on my computer at work, and use ssh in an xterm to start x-clients on one of my computers at home, displaying the windows on my computer at work.

Is it possible in some way - preferbly without any additional software - to disconnect the x-clients from the x-server without terminating them, and reconnect them at another computer running an x-server (another of my computers at home)?

If it can only be done without using ssh, by starting the clients in some special way (ala nohup), or if I'll need to use some extra (like screen) or special (???) software; I'm open for that too... but as I have the clients running right now, I'd prefer to disconnect them as they are if possible.
