Bathsheba, that is brilliant!
With a pantograph you can draw lines just as easily as you can cut or engrave and then you just have to scan the lines into 2D data.
As you mentioned with the digital image, you could then measure one place and scale accordingly.
This may be the "cheapest" solution.
BTW, I would rather problem solve (than work), too!

Have you a pantograph? and a drawing tablet?
