You'll figure out the renders. I appreciate you posting the RAL colors.
re: numpad being split out
I use a numpad (as a separate device) and buy coverage for it every set. Split it out or don't, either way is fine for me. What no one likes for GMK sets is the TKL coverage still costing USD 120+ and the numpad on top of that (GMK eclipse, fro yo, cafe as planned, can't remember firefly price), with it being marketed as "saving money" when custom color sets like GMK violet on cream are under 125$ for full coverage (sandstorm also was thanks to DUDUDUDU, voyage, 8008 was 130, there's others...) with the whole set in there, and two of those I know had MOQ at 250.
Jamon, striker, 9009, minimal all had no numpad but cheap base (99$ USD for all) with numpad kit at 40 or less. They also sold 500 base kits each.
VoC is another great example of pricing:the alternate alphas kit included the numpad numbers, and was still under 75$.
