Brian's knob board is fine as-is. After messing with the LED spacing myself, it really didn't change much. I wouldn't expect Brian to make any changes in the design.

I'm quite happy with the overall lighting and diffusion of my knobs and buttons after having frosted the LEDs by griding their tops (Brian's new kits will have pre-frosted LEDs) and using the white plastic as a diffuser behind the knob.
