Gauging interest in making new alternator voltage regulators

I found I hadn't thrown away my dead OE points regulator. Looks like making a backing plate that fits this and contains a solid state regulator circuit board would not be too hard - but copying the case itself out of steel would be tricky. What would peoples' thoughts be on a vacuformed plastic cover that mimiced the original steel? I know a guy who does a lot of movie props who could probably do some pretty convincing covers, while the grounding and heat sinking would be taken care of in the backing plate.
