Of course you can buy all sorts of new and fancy keyboards, if you're so inclined. If you're more like me, meaning cheap and quite content with the esthetics of the original Cherry keyboards, you can get this done without any soldering, since they are not plate mounted and you can easily take the switches apart. Also, blue cherrys have the same light springs as browns, so this expands your options as well.
My suggestion is to buy two cheap old Cherries:
One G80-XXX with blacks, one G80-XXX with blues or browns, and one of them should have the letter "H" in the model name, which stands for doubleshot keycaps. Essentially, this will set you back about 30-60 Euros in total on ebay.de, but you can sell off the keyboard you don't need afterwards after swapping the springs, or give it to a friend as a gift (more like a friendly gesture of "here's some heroine, it's great, you want to try?"). I'd suggest a G80-1800 for the keyboard you're gonna end up using, because they're a bit more special than the G80-3000 that everybody's got - but your mileage may vary, and the location of the entf/einfg/pos1 etc. keys is a bit sucky.
