Looks like some core Xorg concepts should be reworked to support this.
Like plug/unplug new video hardware "on fly" in running copy of Xorg.

On another side, probably, it will be not to hard to make it work with
Xinerama (with all xinerama limitations of course) and Xserver restart.
But I really have no idea how to handle disconnection of hardware from
running Xserver.
