If you are still working on this I would like to throw a hypothetical wrench into the basis of the poll.
The only way a romantic mod would make sense would be to allow the player, Ramza, to pursue a variety of relationships. I am not sure how difficult it would be to check dialogue choices in past events, I know the vanilla game does it at least once, such as when you are introduced to Algus/Argath.
Ramza should be capable of romancing all of the people in the poll, at the same time. It would really help cement his status as a heretic at a time when the church is undergoing their attempt at a monogamist reformation.
Also I have always wanted to be able to talk Miluda down instead of having to kill her.
I do not know how hard this is, probably very, but I think it would be awesome if events could be triggered by using a specific ability on specific characters, such as the Orator's abilities. It would be a good way to allow pursuing romance options at your own pace, and a natural way to try to convince Miluda to stand down.
Sorry to necro, but it was on the first page and I strongly disagree with most of the posts so far, so I wanted to add my two gil.
