I would have no issue with this, but I have to wonder... whats the point? The way I see it the permanent damage is already done! They would be VERY easy to kill because they just sit there and look at you. I would venture to say that even in just two tanks of diving I could have killed every one of them on that wreck. Problem is tho, when they have ZERO predators (other then humans) to control their numbers, in a few weeks that same site would be covered in them all over again.
