I think you would be wasting your time trying to create some sort of pattern with the balls and thinking that you can have an advantage. If someone created a machine that racked the balls EXACTLY in the same position every single time, you would still get variation on where the balls go, simply because you will NEVER hit the cue ball exactly the same way every time, at the same speed, height, English, angle, or position every time.
There are too many balls colliding with too many rails, making second, third, and fourth contacts along the way. If you can show me that racking the balls in a particular order is truly an advantage, I would be stunned. It's like some people are looking for a secret to how the break works, when there are simply infinite variables involved. On top of that, not every table is the same, not every ball set is going to be the same, some are waxed, clean, and others dry and dusty. It is misleading to those who believe consistency can be achieved when putting an order to the balls.
Sure, you can aim to make the wingball or apex ball, and you can do that relatively consistently, but if you could do it every time and get the same layout every time, you would be a god. Spend more time on the tangible, practical parts of the game. All this effort spent on perfect racks, perfect tips, order of balls, etc etc, is wasted. Focus on drills, competition, stroke, and confidence. I know there are players out there who know this, and don't waste their time on the miniscule parts of the game that are simply too unpredictable. Besides, if you could get the same layout of balls every time, where lies the mystery and challenge of the game?
