I hadn't considered a "Frankendistributor" such as you mentioned but could see a case for that in some (limited?) instances.
Interesting that you mentioned the Chrysler electronic ignition system as I ran across a web page today outlining how to activate it using points. A real plus to that conversion is that if it fails you take it out of the circuit and get home on the points. The bad part is that in order to work the points need to be set so they barely open and with the poor wear characteristics of the rubbing blocks on point sets that are currently available they may still need to be adjusted maybe a few times per driving season. On the other hand being set so they are barely open may relieve some of the spring tension so the wear may be slower.

you could "Frankenstein" it using a Honda or a V8 cap and skip every other post.
or a very very abstract idea.... apply voltage to the distbutor and use the cap and rotor as the hall effect switch, and by using two coils with two outputs, one can be fired and send spark to the cylinder that should be fired and one to the exhaust stroke of the opposite cylinder, then fire the other coil when the other two cylinders are on the appropreate strokes ????
I think my head just exploded! That is some very "out of the box" thinking and while maybe not the "simple" project that I'm looking for it would be an interesting experiment.
I'm used to Hall effect ignitions using a shutter wheel of some sort so imagine my surprise when I found this today, an ignition module that uses a Hall effect switch that detects the existing distributor cam so no shutter wheel involved. (See link below and check the instruction .pdf for a little more info)
Since all I'm looking for is a point set replacement that will simply trigger the coil like points, rather than a complete electronic module such as the one above which wouldn't fit in my distributor anyway, I will now spend some time researching Hall effect switches to see if something suitable, to me, can be found. I love the internet for projects like this but sometimes it just takes forever to figure out what to ask for.
Sounds very much to me that you are running the points cam dry.
There should be a small piece of felt wedged between two small uprights in the dissy that, when oiled with sae30 or similar, keeps the rubbing block from wearing unnecessarily.
Of course you can simply add a smear of light grade grease on the cam as I have done many times in the past with good results.
I have also struck in the past, requirements for mods that are simply because " man it's cool eh?".
An oil wick would have been a nice addition but Lucas didn't go that route.
I'm still using the tube of Borg Warner cam lube that was "issued" to me when I went to work at VW in the later '70's. It doesn't take much to lube a rubbing block.
"I have also struck in the past, requirements for mods that are simply because " man it's cool eh?"." How true, and all of them came with "unintended consequences" as my friend would say.
Just checked online, Jaycar in Aus still have stock of a " high energy electronic ignition" system for around A$55.00.
Apparently takes a mass of differing inputs( selectable) and also programmable to suit whatever dwell etc takes your fancy.
Just thought it maybe of interest to you.

Ps there are stores all around the country so you may have to check which has stock as I believe they operate as a franchise these days.
This is obviously a rough draft but basic principal. and if some how you could make the cap and rotor make physical contact then this would be all down hill from there and they do make spark plug cable splitters that have their own posts (usually they are used to switch coils but they could be used in just the opposite. in theory, all the advances would still work just the same.
By how long the cap is in contact with the rotor. So by changing the width of the contact surface of the cap contact...... find what the original dwell should be then use that fancy circle math to find how long that angle actually should be at the circumstance “point of contact between cap and rotor end”
That is some very "out of the box" thinking and while maybe not the "simple" project that I'm looking for it would be an interesting experiment.
