Ok, so you've got some life events. The move would be the biggest detractor for me so I get where you're coming from there.There are dozens upon dozens of factors that relate to how I handle working on this car. Very very few of them are directly related to the car and are generally not talked about on here, but lets look at a couplefor shits and giggles.
My garage is too small. My lease is up this summer, so we might move, we might buy a house. To do the bodywork I will need room for a decent welder, bottles of gas, either a plasma cutter, a decent sized air compressor, or (more likely) both. All of those things are expensive as fuck. I will need room to move around the car and crawl through it. Say we do move, without working lights I will have to spend money to put the car on a trailer again. At some point in the relatively near future I am going to have to work on wedding plans.
My life is just too damned unstable for me to start on big projects, so I am not going to. At the same time working on and driving this car are my two biggest methods of relaxation, so for me to not work in my garage is damned silly in my mind.
From my point of view three people who mean well but have one small fraction of the story are trying to convince the guy doing all of the work and who sees the entirety of the story what to do. I would bet that everyone telling me I am wrong has a manager or supervisor at their job that does not understand several key factors of their job that nevertheless tells them how to do their job.
Let's look at it another way. How would you feel if I told you that the stitching and the colors you used on a project for a customer were completely wrong and you needed to redo it from square one?
Would you tell me to fuck off? Would you ignore me? What if I kept questioning you on why you were doing it that way?
We may have only a fraction of the story, but you have three people who are very comfortable with electronics telling you its better to repair the existing infrastructure than run new stuff. Experience counts for something, whether you choose to believe this or not.
Your example is not valid. If I'm doing a job for a customer, I would be doing it to their specs for colors/materials. As the craftsman contracted for the job, the method of execution is up to me. If the customer wants to try and tell me my methodology is wrong, they can pound sand, unless they themselves are considered a resource in the topic. If a master upholsterer told me I was doing it wrong, I would listen and ask for assistance.
I equate your question to a rookie tech asking a master tech how to accomplish a task. You however continue to justify why your view is superior to the expert opinion you sought in the beginning without presenting anything more than "I don't want to do it that way" as rebuttal.
For someone who has proclaimed them self to be competent in reading schematics and troubleshooting circuits, you are sure going out of your way to not even attempt this.
