I'm a total novice at this parts creation technology utilizing computers, laser, etc,...so please excuse my very limited knowledge with this inquiry.
I'm building a stone arch viaduct that hopefully looks something like the famous Thomas viaduct in Balt. I have the backbone structure of it made from expanded PVC foam. My thoughts are to create the decorative 'skins' in some sort of molded plaster or another product. I would need to create a 'plug' to make the mold that would then create multiple thin arch duplicates.
So my question is, could a photo such as this be used to program a laser cutter to build several plugs for the molds to create the multiple arches?

Two arch shapes I have in mind,..
