Considering that it was done in Harvestella (a game on which XIV devs have worked on), I think the option for it would be pretty cool.

I wish we could have a pronoun/gender choice considering a few NPCs both in-game and in EE have it this way already.

Sure, adding a whole new pronoun to 13 years worth of text might take some time (even though your gender only appears, or even appears to be relevant in dialogue a handful of times only) but.. heh.
About whats already in the game right now, Male or Female is just a character setting byte or something. I hope the option to pick which one we want will be available in the future!
