One Pocket Guy, actually you have posed a good question. It is always good to ask; "what if", and I believe you have come up with a new one, at least new for the current generation of Cue Ball Foul Only babies.
To answer your question: I believe under All Ball Fouls rules, it would be in OP a 1 point foul, loss of turn or better yet a 'concession of turn', and the ball remains in position, or option to be restored, for it was an intentional act.
There are a few tournaments that still play All Ball Fouls, but I believe the players either have earned their right to play in them or are invited, and thus are smaller but prestigious tournaments. Therefore are able to have the matches refereed.
The early historical general rule writings were wrote much simpler, for at that time 14.1 was considered the game, and the championship game, and they were refereed. So much was put on the referees, and not so much detail was put into the written rules.
But with that said, your act is intentional, and intentionally disturbing an ob could result in screwing up the position of the balls in your favor or not, thus if I were the referee, I would call an intentional foul, and under our rules 6.6 the player would have the option to have the balls restored. Which I would like see upgraded to have a further option of having ball in hand, and of course our rules can be subjected to unsportsmanlike conduct, in which case I would offer up to your opponent the option of ball in hand.
Also, if one wanted to ploy this trickery, that intentionally moving two or more balls is a loss of game, which I would call. Surprise, Surprise! Check rule 10.2, I believe this would or could be applied in this instance. But, in any case I would apply it for it is such a flagrant unsportsmanlike act, of which a referee under our rule 6.6 has the discretion to do so. Whitey
