i think you are diving too deep into problems that don't exist. just fix whats broken, if its running right just keep maintaining your bike.
A big problem you see to the rise of problems in general is that there are a lot of Vulcans being brought back to life after years of sitting and neglect. these bikes were made to ride the snot out of em, and not be parked for long amounts of times.
Since I notice you are becoming paranoid about everything on your bike, may I make a suggestion... either buy a parts bike, or do a 100% frame up restoration... or do both. personally if I was as worried about all these issues I would go with at least a second engine and rebuild it with brand new crank, pistons, valves, springs, bearings, TOC Cam Chain Tensioners... yadayada... then have complete brand new engine. Replace all the factory wiring with a custom harness, Get a TPE Stator, MOFSET R/R, an ignetech cdi box with ignetech racing pickup coils, a pair of Acell Super Coils running NGK wires and plugs. Top the whole electrical package off with LED lights and a HID headlight and a n aluminum cooling fan... Then move on to the suspension with Progressiv springs front and back. Get a final drive from a VN1500 along with the drive shaft, and swing arm... have a machine shop combined the front half of your vn750 swing arm and drive shaft to the vn1500 back half so you can mount up the vn1500 final drive... now presto, you have a flawless brand new bike for only 9,000 bucks that should last you another 40 years or so...
OR you could just let go of your paranoia and fix the little problems you have right now, and keep maintaining your bike like the book says to, and ride for many years to come, and just worry about problems that might happen when they do happen.
Bottom line... Do what your wallet can afford.... We have a member on here that claims well over 200,000 on two bikes, one bike had (IIRC) 160,000 on it before he sold it with out even touching a stator. but then again like I said.. he bought his bike new, and never parked it for longer than a week.
