Hit another 175 balls with the swing change in mind. Did not go very well. I keep getting laid-off on the downswing. One of two things tends to happen: 1) I keep the right elbow too "tucked" and, combined with the deep turn, I come in too flat; or 2) I get into an OK position at the top, but in the transition I drop-in too much, leaving the club way too behind me without much room to come into the ball. I was beginning to think that this experimental swing change might not be for me, so I hit 25 balls with the less-deep and higher hands over the right shoulder swing. Everything went well. I might give the proposed swing change a bit more, but not looking good thus far (400 or so balls in).
