The Assembly Base Kits that have been offered recently have solved this problem by grouping Ergodox and 40's users with their own base kit, so if it fails, the main base kit will still be supported. Check out the Assembly kit in Oblivion V2 for reference.
Edit: Never mind on the 40 bit kit, I just saw your previous post mentioning Space Cadet
i really enjoy the colors in this set, but I use ortho boards. So I tried to see how to assemble a planck layout with base and the novelties, and find it hard to visualize. Any chance for a render? I was thinking about the following:
R2 left: teal R2 novelty, R2 right: Del
R3 left: R3 orange novelty, R3 right: normal '"
R4 left: R4 red novelty?, R4 right: red super??? (or end, but both not ideal. end would keep the right modifiers all alpha case color though)
R4: ctrl, code, alt, super, red ring novelty, 2u numpad 0, teal R4 novelty, cursors
I have the feeling this will be quite colorful, and I'm not super happy about the enter and 2u. But this would have the "traffic light" on the left modifier side. Anyone came up with something better?
/edit: accented cursor keys could actually be used as lower/raise and return, so the only issue is the missing 2u spacebar
