i think there are many more individual German keyboards with brown stem than there are US-EU keyboards, would simply buying a German keyboard and replacing the keycaps or using sticker keycaps work? That is my question, amazon and other german distributers seem to sell the brown stem keyboards individually, and I cherry is a german company? so this would make sense.
The main problem is the keyboard layout where germany use a "QWERTZ" so a complete new set of keys are required, it is still cheaper than buying a filco or hhkb pro2 for UK people like me, since germany is in the EU. So I could buy a german QWERTZ brown stem keyboard and a british QWERTY blue stem keyboard and just swap them and still be cheaper than importing the expensive japanese keyboard.
But I am unsure if the keyboard will have the same mechanical layout when using it when plugging it in?
The US G80-3000LQCEU is very hard to find but the German G80-3000LQCDE are more widely available, just find a german speaking/reading friend to help buy the board
