Ed & Group,
I brought up the question of possible use of Solid State Relays (SSR) to replace the
electro-mechanical contactors most of us use in our flying electrical systems but I need to depend on the smarter "EE" (Electronic Engineer) types of our group to tell me if this
would be a good idea......

I tried using one of these. I know my situation is different, in that I'm using a generator, not an alternator. The issue I ran up against is that the regulator could not sense the bus voltage, and never turned on. It least, that is what I suspect the problem was. I wasn't getting any voltage out of the regulator with the SSR installed. I replaced it with a fusible link, and now everything works just fine.
