You may find that is a bigger hassle to clean than it is worth. If your pork is done, it really doesn't take much to pull it. Just have some well insulated gloves and you can do it just as fast. Is the brisket going to be pulled also? If so I would look at chuck roasts, I think you can get those cheaper and would pull like the butts.
