A lot of what makes the X0 player great, though, is exactly the part that definitely DOES NOT deal with PAL, and that's the NTSC decoders in parallel, and all that other sort of post-processing circuitry. If you have to ditch that, then why bother with an X0? It would probably be smarter to gut a 2950, which can already play PAL discs natively.

I thought the big deal with the x0 player was that it didn't postprocess anything unlike other players and outputed the cleanest possible composite signal read from the disc with a special laser. And since the signal on the disc is already in the composite format it wouldn't need any coding/decoding (maybe those parallel NTSC thingies are used for s-video, component, and/or antenna outputs?). So unless the PAL discs are fundamentally different (not just a different signal format), I would imagine they can be read with an NTSC player, unless it has some PAL disc detection circuit that cuts off the output if PAL signal is detected. So what does happen when you put a PAL disc in an NTSC player? I guess this is a bit farfetched
