Your edit is correct. This is just the key breakdown. I'll turn it into graphical mock-ups next.
I would just add one suggestion to your kits, add a handful of blank (purple?) keys in "common odd" sizes to the "extended" kit; 1u, 1.25u, 1.5u, 1.75, 2.0u. Five blank kits won't add much to the price, but (because DSA profile is row agnostic) it will exponentially increase the odd layouts it will be able to accommodate. For example, split backspace and split r shifts, 1u tab and 1.25 caps lock compact designs, etc..
The other option, is to beef up the blanks into a separate kit by having the keys in yellow and purple colours, plus, adding a 2x 3u split spacebar key; since split spacebar designs are all the rage atm. Going the separate blanks kit route would also help Japanese (JIS) board users.
I really like the way you used the purple and yellow to recall the Lcars interface in an earth style keyboard. Maybe carry it on to the numpad by having the purple go along the top (from the 3 purple logos) then down the middle of the keypad (963 column) splitting it into two areas of different colour either side.
