Your USA-Dvorak for Germans?

Dear Sir, 

I found your great bindings here https://gist.github.com/sergeykish/650839#file-dvorak-de-diff

I am developing similar thing here http://askubuntu.com/q/648659/25388 where you can see the proposal at `Final solution [Sneetsher]`. I have not managed to get the script stable. 

Can you please propose your work process about the thing.
