This is something I was thinking about, too, but couldn't think of a good way to say it.
I guess I'd be concerned that we could go too far with it, and TOs could only be successful if you had a lot of nobles clicking their "Be hostile" links every turn.
It won't be like that. As with most things in the game, the law of diminishing returns will be in effect, meaning that you will need a few nobles actually doing something for the TO to proceed nicely, but after the 3rd or so, the effects become smaller and smaller.
