Metal Keycaps (Mechanical) That Allow Backlight?

[WuMyster]

Is there such a thing at the moment?
OCUK sell your own metal keycaps, zinc i believe, but with my Ducky YOTS coming in, having metal keycaps would look beautiful with it, especially with the backlighting shining through.

Wouldnt want to take out one of the most important features to me. Anyone know of where I could get a set of metal keycaps thatll let the backlighting shine through?

By Metal keycaps allowing light through. What I meant was metal keycaps that actually have the letters cut out and maybe a plastic put in, to allow the light to go through.
This does seem tricky and expensive though so Im guessing this doesnt exist either.
