What you described wasn't a swashbuckler but the poorly trained throwaway character from an old pirate movie. A swashbuckler seems to have always been a lightly armored upfront and skilled fighter that seems to have originated in the period when a fencing sword was civilian legal. the Weapon choices prevent you from doing some of the more traditional fencing styles such as pairing a rapier and a dagger and if you decide to mention the use of the feat Two Weapon fighting. Then the use of such a pair becomes extremely subpar. Basically going rogue is fighting without flair and being a sneaky git as well, which doesn't really fit the image of a swashbuckler. In comparison to 3.5 character classes, your idea wouldn't fit there either.
