While we could only do the 1.25 bottom row keys and 1.75 fulltouch caps lock, there is still issues with them matching the plastics color 100% at least with the beige/grey as there are at least 4 major shades that were used over the years with those. Might be better to offer modifiers pack like the purple to avoid matching problems? With white on black, it is no concern for matching color so probably just the fulltouch caps lock, 1.25 and 1.5 control and alt, 1.25 win and menu... and maybe just like one big Euro kit for assortment of harder to find alpha character keys plus ISO left shift and enter?
