Meh. Those guns are also ridiculously underpowered IIRC.

Iron Kingdoms is a Steam Punk setting that uses turret, clockwork, musket and various other firearms in its system, while still maintaining a modicum of swordery.

I believe there is a module (or maybe a whole system, not ENTIRELY sure) called Seven Seas or somesuch that deals explicitly with High Sea's adventures and swashbuckling. Might be worth looking into...
