That plate is just a normal ansi 108, why not just build a fully programmable board yourself and just customize it how you want it?
I'm not sure what you mean by normal ansi. It's a non-staggered design so at the very least I need a custom PCB. It's also non-standard board size I believe.
It would also be nice to push it and find a place that can build scissor keys.
But the main answers are time and laziness.
