gcardell, OP asks a question and if you can't answer it then STFU. Posting humorless pics can be annoying the third or fourth time around.
To the OP, have you thought of going bespoke? I can't imagine it being too difficult to sneak in a few cm's at Lobb's or Beluti's if you can engineer the shoes from scratch. Personally, I think you have a solid height. Any taller, you won't be able to help old ladies crossing the street.
