Well, If I was going to do french doors, I would do it like this, with one door: http://www.jzconstruction.com/photos...fter%20(1).jpg
with one 3 .33 ft french door in between 2 fixed panes. I do not really like the look of four equal panels, and it does not seem practical to have friench doors where each door is 5 feet wide. It would be way too heavy to be supported by the hinges. I supposed you could do something smaller on the sides and have each door the standard 36 inches. What do you guys think?
