Placing the live rock as long as it doesn't pose a navigational hazard probably wouldn't be a problem. As soon as it hits the sea floor, however, it becomes "live rock" which is completely forbidden to take without a special permit. It doesn't matter if you put it there, it is illegal to take.
I'm sure someone will say I'm wrong... let's hear some input!
