When in my first post I said to get your fore/aft boot set-up checked out, it was because what you said made me suspect your boots might have too much forward lean. Your pics then reenforced that suspicion. Especially number 1. You just can't get your outside leg long and strong with that much forward lean. Even when you try to stand tall and center balanced, your outside leg remains overly flexed, as it is in photo 1. It has no choice.
Check out this picture. Here I'm purposely standing fore balanced, with all my weight on the balls of me feet, and pressed firmly into the front of the boot cuff, and my shins are not pitched nearly as far forward as yours are in that last photo you just posted, standing relaxed.
These boots were set-up for me by Jeff Bergeron in Breck.
It appears that by putting in the spoilers, trying to fix your volume problem, you may have created fore/aft alignment problem. I think you now know that, now that with the new liners you've pulled out the spoilers and felt the more upright stance. You need to get your fore/aft set-up dialed in so you can ski strongly and efficiently. You can play around with self experimenting, or you can just go see a professional, be done with it, and get down to skiing.
