A pirate themed DND campaign!?!

I won't lie, my mind went and made a pirate themed DND campaign idea. Basic synopsis is pretty similar to One Piece, where an Infamous pirate, before being executed, told the world of his map and will lead to his treasure. Since then, various pirate factions have been made and are trying to find this treasure.

You and a few other players are a new crew, and your choices can eliminate all of the factions and make yourselves THE last standing faction; doing various quests and having plenty of patience to get all factions to work together in harmony; or a weird mix of the two where you team up with one or some factions to eliminate the rest.

All of this as a way to find this map, the treasure, and become the next legends of the seas.
