Yes, it is possible to play the whole "Tales of a Sea Hawk" storyline as Danielle, or any other character of your choice, male or female. Dialog and questbook files have a lot of preprocessed variables to account for that.
The reason I missed Douwesen was that it was written as "Duvezen" and I didn't recognise it! I've corrected it, and "Hopefully", in the attached English "smuggler_line.txt". It also has "she" and "her" changed to preprocessed variables, and I've added lines into "quests_reaction.c" to fill them in using 'XI_ConvertString(GetMyPronounSubj(CharacterFromID("Danielle")))' and 'XI_ConvertString(GetMyPronounPossessive(CharacterFromID("Danielle")))'. That has to be enough to allow choice of male or female characters, otherwise the rest of "Tales of a Sea Hawk" and all of "Ardent" won't work.
Also attached is Russian "pirate_line.txt", converted into "New Horizons" format. There is only one place name which needs to be changed - Khael Roa should now be "#sisland_Khael Roa#". Please check that I got the right line for the title.
