I created a layout based on similar assumptions a few years ago. Blog post: https://kozikow.com/2013/11/15/the-only-alternative-keyboard-layout-youll-ever-need-as-a-programmer/ https://kozikow.com/2013/11/15/the-only-alternative-keyboard... (including OSX implementation). I also created Linux implementation: https://github.com/kozikow/keyremaplinux https://github.com/kozikow/keyremaplinux . It's also targeting "special" keys rather than letters. The difference is not using modality, but utilizing the right cmd (or the right alt on linux) to activate a layer with all special characters. Conflicts with qwerty are minimal, so you can install it on top of qwerty.
