once you start to add windows, vents, doors, etc. you will probably end up with a lot of unique components anyway.
Not to mention the off-module oddballs and the inside corners. Nevertheless, I like your approach since it permits one to array the tops along the slope and the bottoms along a level plane, and I would not have to go in and adjust every panel individually.
Also, I think that just a few component styles would take care of 90% of the panels on any one project, even on the large-for-me 200,000 sq. ft. buildings.
