Hi Dave,
I think a two-piece resin roof (or half roof) may be the best approach if future needs arise in sufficient numbers, but I would have to make completely new masters - a task I've been able (and glad) to dodge so far. I have in mind the lower roof parts with a deep channel down the middle, not fully cut away down to the ceiling level but with a bridging layer thin enough to be cut out at a later stage if so desired. The upright sides of that channel would provide faces to which a clerestory glazing sheet could later be stuck, each side. The central roof and its rounded ends, with the whole of each side completely open (under the part with a straight top) would be the other component, the end sections being solid and deep enough to fill the channel ends in the lower roof. A rebate around the edges of the open sides of that upper roof piece would seem sensible, to provide for reasonable firm location and bonding of the glazing. The sides of the upper roof piece could be deliberately inset sufficiently compared to its roof to allow for a thin further overlay for those not wishing to use paint and pen to mark out the windows and panels.
