From what I saw last night you'd have to modify Tims NewFace to fit in a knob the same size and the original empeg one. It could quite easily be done in a milling machine, and I don't think it would detract from the design at all, but the knob that Tim has come up with is really nice to use, and does look quite good. I'm really looking forward to seeing how it looks with some LEDs behind it! I'm sure he can do a brushed finish on it for you too if you ask him nicely . I actually think the Alpine knob would look a bit silly on any of these faceplates, but then that's just my opinion.
