I think letting TC and econ run it behind the scenes is a good idea especially since we can still control avatar movement for some extent.

Stig's plan also has some merit and I have no doubts that some of it might end up being incorporated, but I wouldn't like to see the exact course of events being laid out before they happen to everyone, as that breaks the immersion and thus fun.

That said, Hans won't have long to live at that time anyway, so throw anything you like at him.

Also, as a personal suggestion, and you may ignore it, it would be interesting to lose all of Outremer or all except say Antioch. That way, it allows us to form a true crusade again later in game.
Further, if you need help with console, do PM me. move_character specifically can be quite useful and I can also mod the files to allow higher rebellion rates as Stig suggested and even force the AI to build certain buildings for instance or train specific agents.
