I have found in my years of various game modding that there is two keys to sucess for a mod. The first is the simpelest, the ability for the game to be modded in the way you wish. From the ... scope of what you want to do, KotOR is probably not capable of what you want to do.
The second is far harder for any person to accomplish (from what i've seen) and that's to have the ability to do the work yourself. What can you do to help this mod come to fruition? If idea's/story/script are your only capabilites, abandon all hope ye who enter here. I'm not trying to be mean, I'm just offering the advice that 'It's better to offer somebody your services as a modder, than to ask for somebodies services in modding.'
You are incorrect on almost all fronts there. Kotor is a great place to do storyline modding, I am making a storyline mod myself at the moment which already has its demo released. I asked for help and I got lots of it, it wasnt that way in the beginning though.
My first mod was Reign of the Sith, the first storyline mod for Kotor 1, everyone said it wasnt possible and i released it, did all the work BY MYSELF. If you dont have modding abilities kotor is the esiest engine to learn in. I have a Storyline Tutorial, however somehow it dissapeared but you can find it on
www.kotorfiles.com) in the forums just check under the tutorials thread. In that I outline everythign, one of which being organisation. You should always ask for a team but if you do, know that you have to be commited to the idea because you are involving more people than just yourself.
I like your idea and I think it sounds great, keep trying, look at my tutorial, because it IS good to have some ability in modding, I am an expert at module editing and am an advanced scripter.
Remember you can ask ANY scripting/modding questions here and the best people will answer them. So dont give up all hope, but get all hope. Deffinetly recruit members though. Its all in my tutorial.
Best of Luck
