Every week, I'm greasing the groove with DE squat work so I'm not worried about detraining my comp. stance squat. And all of those things you said they would work good for are issues I have with my comp stance lol (feet a little outside shoulder width, toes pointed out a lot, low-bar (Ripptoe low-bar).
I also remember the time I made the fastest squat gains was when I did Oly squats for 3x5 after doing the main squat work when I was doing a Western periodization scheme with a team of powerlifters. I'm sure it's not the only factor, but it might be one.
