I did this on my auto Integra.
I bought an ITR carbon shifter bezel and the opening is smaller than the OEM automatic shifter bezel. Since the ITR piece wouldn't fit over the shifter plate (the piece with the P, R, N, D, etc indicators) I removed that and used an ITR boot to cover the hole it left behind. I also have that same Razo knob. I think it looks good and works great. And it isn't hard to figure out what gear you're in either. If you know your way from where P is, then R and D is easy to shift to.
You can see here the difference in size of the openings:
