I agree with Keith that this rule change would just add more luck into the break. If the tables break hard, then the breaker could actually be at a disadvantage.
If they want this rule change to fly, I think they should add another rule in conjuction with this rule. If the breaker pockets a ball on the break, the breaker should have the option of accepting the ball made and the table layout, or giving it to his opponent. I call this the "switch" rule.
For example, if I make a solid on the break and the layout of the table is such that it's almost impossible (for me) to runout solids (or if I don't have a clear opening shot on a solid ball), I can call "switch" and force my opponent to shoot solids with the current table layout. Unlike the "push out" rule in 9ball, my opponent does not have the option of giving it back but is forced to play solids. Of course, I would relinquish my turn at the table.
This way, the breaker is not at a total disadvantage if the table layout isn't very friendly after pocketing a ball on the break. This would also create another layer of strategy to the game...deciding whether you should "switch" or not. This decision would not only depend on the table layout, but also your skill level as well as your opponent's skill level. If playing Efren, you probably don't want to ever call switch, no matter how impossible the table layout, since you just don't want Efren back at the table.
...just another crazy idea. I'm filled with them.
