I'm opposite with Revan and Exile. But My DS Exile plays a major part in Revan's conquering the galaxy in my own little story. My Exile is fun to play and fun to write about, but I haven't gotten a real feel for his character the way I have with Revan. But that may change if I write more about him.
As for your mod project,. maybe you should post a to do list and keep that updated, so you will not only keep us updated, it will help you keep a focus.Listing can be very effective.
Another thing, what Sith Holocron pointed out, don't get hung up on the names of all the star ships, or, don't get hung up with Kreia's final dialogue or all the details. There's no rule that you have to conform to every part of it, as long as you keep the spirit of the game. You're not making the characters liars, it's just minor inconsistencies that might crop up in even the best works. Some may not like that, but it's your mod, and they can make their own mod if they don't like what you've done. Ultimately you should be making the mod that you want to play.
