I've fought a very similar move and still fight it, especially with the driver. For me, it is a stand up throughout the downswing to fit the club in for a few reasons. The first thing I found was that I was standing the shaft up into impact and had a poor out hand path with premature right elbow straightening(throwaway). When working on a better hand path, I found it near impossible to get it unless I cleared the left hip more. I also needed to have a better set up which was to not bend at the hips as much or stand a little taller and drop the chin down more. I then use art's right hip bumpy back, but then also set the left hip by turning it out which essentially feels like spreading the pelvis apart. The backswing is then just a turn around the base of the neck/upper back. The downswing is still much a work in progress, but it starts with the hands working away from the target and down with the left hip/leg turning around sooner but leaving the right alone and only being pulled around(I don't even notice what the right hip is doing). At some point into the downswing I work the left shoulder up and back which allows the hand path to stay in close to the body. I have done pretty well with this and can actually get to impact with a bent right elbow and open hips, which is something I never could do before.
Sorry for the ramble, but hopefully some of this helps you out.
