We haven't discussed that yet, because that would require some actual storyline content to be written which is definitely more time-consuming to do.Kind of tired, might have missed it in my skim, but has the idea been floated (heh heh) to play as Pre-curse Davy Jones? Like, the lead up as a mortal to him taking over as the big bad monster of myth? I think that would be a pretty sweet option. You wouldn't start with the Dutchman in this case, of course (although it would probably be pretty quickly if I remember his history right), but at least it would be able to have a storyline to it. And Calypso. Calypso kicks ass. Rallying the pirate brotherhood. Gathering the necessary magic widgets to trap her in her human form. Lots of good stuff there for possible use.
Would certainly add to the game though and if somebody would be willing to do it, I'd be happy to support that wherever necessary.
