Man O War public event?

So here is my idea. I love the skull forts and I was thinking a event where we would have to face a man o war would be nice. Imagine the skull in the sky pop's up and you set sail toward it, as you get close you can see it is a man o war. You ready your crew and cannons and get ready for battle. The man o war opens fire as you get near as the forts do, you engage in battle and once the ship and crew is defeated a whit flag is raised signaling the surrender of the man o war and you are able to board and get the loot. Just a idea but I think this would be a very nice public event and a great opportunity for other's to work together.
