This is not a layout idea, but a suggestion based on a recent personal experience.
Recently I noticed my track was lower than normal, so checked my PAP, and sure enough, it was. My experience told me to get the thumb out earlier so I spent the next two weeks focusing on that, and better ball motion returned.
If I were you I'd try that because the results were immediate and obvious. Staying behind the ball longer and freeing up the arm swing were critical to me using less grip pressure and fixing the problem I had slowly gotten into.
Layout is third down the list of importance to ball motion behind 1) the bowler's speed, release characteristics, etc, and 2) surface texture of the ball. When we track that low and have so much tilt we "paint ourselves into a corner" so to speak, and limit what layout options are there.
If you train yourself to work on #1 above then your bowling will open up options rather than limit them. Just an idea from personal experience and not criticizing anything about where you're at.
