I am buying a VX soon and this will likely be one of the first things I want to tackle as well, so maybe we can put our heads together and see what we can collectively come up with. I can do CAD design-work as well fabrication and soldering.

The main things to tackle are finding the proper luminosity of LEDs and sizes, watts etc. In the Russian's post you reference it also looks like the folks at UFO either re-made or modified their own light board for the back lit needles and panel facing. This is something I would not know how to do off hand but where there is a will there is a way and I know that people with other vehicles have done similar projects with making their own PCBs. (printed circuit board)

Lastly, I would like to re-design the semi-circular dash rings themselves and do them in brushed or anodized aluminum which would be laser cut and etched. I don't like the fake carbon fiber plastic nor the fonts for the numbers as they both look very dated. I would want something much more fresh and futuristic looking. The only caveat I see is that the numerical locations and hash mark angles would need to stay the same so as to not require any other sort of recalibrations of the servos and how it relates to their functionality but there certainly should be no major issues with changing out the lighting and panel faces themselves.
