Number 3 would sound like the cool idea, but maybe if you try it, you should get others to write some of the other stories? That way, you'd be sure that the tone and writing style would seem different enough to be a different person telling the story, because it actually was.
But anyway, sounds like a cool idea. I was going to make like a little journal of my character's travels and observations of his time in the Kingdom Isles, but well, I don't have the time.
I wish you luck.
