like you are thinking on the right track!
I fought for years to get rid of the fundamental "face the ball at impact" with NG. They finally did somewhat after I departed.
Shoulder turn means to most people actually upper torso turn. If you asked most what shoulder turn is they would demonstrate the upper body turning away and through, while the shoulders are going along for the ride.
All top golfers today that I have seen have their hips and upper body open relative to the target line at impact. Why would anybody want to do it differently? I think it is even much healthier for the body to do it that way.
The turning open even will help you accomplish the bent trail arm at impact as the trail shoulder will be closer to the ball at impact if the upper torso has turned open. Hurrah!!!
