Don't Kluge-up your A. If it is "different" when you have a problem on tour, there might not be anyone who can help you. Keep it original and get out of the way when you open the hood.
I'm weighing this topic as well, for my own car. And while I understand your sentiment, I would like to share a different perspective.
Maybe I'm reading too much into your 'get out of the way' comment, but instead I would recommend being / becoming the expert on your car.
Example: I went to breakfast last Saturday to check out a local club. A bunch of really great folks with really great cars. Unfortunately, one car didn't make it to the meet, and was left at a gas station. After breakfast a rescue party went out. About 8 friendly, well-meaning guys. Nothing against them, but only two were mechanically inclined and knowledgeable.
And those two were both fiddling with different things, to the point that we don't know what actually got the car running again. The owner was able to drive home, but it still wasn't running right, and nothing was learned to guide future troubleshooting.
And maybe it's just my personality. I don't mind a little help now and then, but I want to be the one working on my car.
If I put in an electronic ignition, then I will do it myself and know how it works, and how to troubleshoot it.
If I stick with all original ignition parts, I'm going to be the one who knows how it works and how to troubleshoot it.
Either way, I plan to carry spares and appropriate tools.
After all, if a group of us go out on a run and 'that guy' can't make it, then what?
My feeling is that the A is kind of a fiddly car, and the driver should strive to be capable of fiddling.
