Gauging interest in making new alternator voltage regulators

Can you make something that slips into a stock case? Otherwise could we send ours as a core for a retrofit? I've got the one I took out I could send down for a test fit.
Yes, it looks like my best option for a restoration type regulator would be to have a base that fits the shell for an OE points type regulator, then have an option of a plastic cover (molded from an original metal one) if you don't have the shell.
