I would be potentially interested in such a project. I am skilled at editing, and could help with the dialogue coding. But I am a poor creative writer, and would be bad at writing dialogues. However, I am never lacking in ideas and could help with the overall story development.
Lastly, I would be of little help with advanced coding (e.g., area creation) which would be way above my Infinity engine knowledge (this would be my first mod).
This idea sounds good and would be a fun project to do.
