Man thats really awesome. We have alot in common. I picked up golf in 2007 and had back surgery 2 years later. I was out my entire 3rd year pretty much and when I came back I tried stack and tilt, right sided swing, some other stuff all to help my back. I also thought stack and tilt was way better for my back than the traditional way to swing. Glad you are coming along and the swing has some really good pieces.
Also like me where I pick a million things I hate about my swing I wouldn't be to hard on yourself through the ball looks pretty good to me and thats what matters. The more I play the more I realize if I can just trust what I'm doing and not get so focused on the bad shots or swing changes I can play pretty solid golf. Obviously you don't need any feedback since you know the pieces you want to work on. The shut face, bowed left wrist, and shortening up the swing some is what I would focus on to help eliminate your misses you don't want.
My other suggestion is to just enjoy the game and trust your swing. No reason you can't play good golf from where you are now. I could see you being low single digits with your current swing easily.
