This is exactly what I attempt to do every time I break the 2nd ball.
I really prefer a head ball break with more power but most of the places I play 8-ball at either have mismatched ball sets, flimsy racks, a rack area that has been beat to death, or I'm playing against someone who either can't or won't give a good rack. Under those conditions, I get MUCH better results with a 2nd ball break.
If it's a bad rack, for whatever reason, you're going to have clusters regardless of where you break from or how hard you break. At least with the 2nd ball break I make a ball most of the time.
