More likely you'll have a 16:9 projector with black borders projecting unto flat black side walls, resulting in a full size back projected image. The CRT people like grainy low res distortion so projecting onto the back of a purposefully bent and distorted piece of plastic should appear extremely similar to a CRT. Of course this turns the problem of a CRT with finite filament life into a problem of a projector with a finite bulb life but presumably it would be easy to swap out the entire projector. With considerable plywood hacking you MIGHT pull off attractive forward projection onto a screen for some games (not many of course) Or if you allow really ugly plywood hacking you can just place a projector screen in place of the CRT, ceiling mount the projector, and call it good.
