I expect there'll be a difference in which layout is optimal when analysing an average python code base with names (variables, functions, etc.) in your language versus regular text in that language, but honestly this is not where typing holds me back. Very rarely do I max out on typing speed for just a few minutes when coding something greenfield. Even if we're talking comfort rather than speed, you'd probably get 99% of the way by laying out symbols differently and leaving the letters and digits untouched.
