While I've read of that, and I'm sure that it can be done, my whole interest in electronic ignition is to get away from worn breaker point cams. At this point in life, with the newest points distributors now being 40+ years old it is safe to assume that they're all worn and most are worn out. The very early "Electronic Ignition Conversions" did exactly that, used the points simply to be the reference point for that cylinder's spark event.
BT, DT.
Spending time on a distributor machine (remember those?) will show you how a seemingly good breaker point cam with little to no visual wear can have large cylinder to cylinder timing variations. (Mopars were the worst for this.) Without some now rare and fairly sophisticated tooling this isn't fixable by anyone. Just the shape of those cams is highly sophisticated, even if you built a breaker point cam grinding machine you aren't going to regrind one without a LOT of trial and error.
