Sure that's possible, but it's not what you are doing manually in your example. For starters; you are only using vertical lines. Furthermore, your adding openings to both the bottom and top of the O, butyou're only adding an opening at the bottom of the A. As you see these are asthetic choices wich a script will not make based on "the shortest distances of the outside border of a compound path to the inside".

you should probably start out by making a list (array) of where the opening (the white line) should be placed and how long it should be for each character (in the font). Then you can let scriptographer loop through your text/shapes and add the apropriate opening to the lettershape.
