How to add elements to instrument cluster or main display

I know there has been a bunch of reverse engineering happening by different people (wk057 comes to mind, but there are others). I remember reading that Tesla uses X11 for the cluster display. Is there any way to connect to the internal ethernet and send an X-window to the cluster or main display? I am looking into whether I can display radar detector information for example as an overlay over the AP car showing on the instrument cluster. I already know how to talk to the radar detector and could add an ethernet port to my little project to send out X-windows to a known address, but what I'm missing is whether that is possible and if so, how? Any information, links, etc. would be much appreciated.
