FOWLR plan, will it work?

Kris, if you mean the Niger then yes. Although mine was only about 4 inches when it went to a FO home. It would occaisionally nip at my hammer, but didn't do much damage. The problem is they will eat anything else in the tank. This includes hermits, snails, shrimp, fish small enough to bite, worms and anything else that moves. I once bought a chunk of rock that was infested with fiddler crabs...they were all eaten in less than a week. Years ago I had a smallish lunar wrasse, and I recall it behaved the same.
If you must have a trigger in a "reef" style setup, the Niger is probably the best choice. BUT....as it grows the chances of having problems with it will increase. I don't believe in the long run you would consider it a successful endeavor.
And, if a trigger decides to go "mean", it could clean your tank out in one day while you're at work.
Remember though, that each fish can have it's own personality, so YMMV
