Boxfish are also pretty aggresive also the trigger mentioned above and niger triggers are fairly aggresive as well. You could also get a large school of dominos they have been known to fend off sharks in the wild. Just keep in mind with a big s.w. pred you're going to need around 2lbs of live rock per gallon to deal with all the nitrates they produce. Also you'll probably want to raise mollies etc to feed it to make sure that you don't introduce any pathogens,parasites etc. Live foods tend to make fish much more aggresive IME.
I'd never try a set up like this but, different strokes.
hth and let us know what you decide you want.
