You could go one step further and build your own keyboard to match your hands as well. I've watched several of these videos and planning on eventually building one: https://www.youtube.com/watch?v=M_VuXVErD6E&list=PLCZYyvXAdQ...
I’m currently working on a hand-wired board. Since you mention pcb development, I don’t feel that hand-wiring is too much work to mention. The soldering and electronics work is trivial (nothing small). I was attracted because it allows me to move the customization into the 3rd dimension with a Dactyl-manuform clone (I’ve actually hacked some closure together).
I’ll make sure to post where appropriate once I’m finished. I’m basically hand-wiring a corne (CRKBD, so there are guides available) only I’ve created a custom 3D manifold fit to my hand.
