Simulating the Second Punic War

[QuintusSertorius]

This is a question related to my Guide, but also my current 1.1 game as well (although I'm over a hundred turns away from it). I'm trying to stick to history within the confines of the engine, which is easy in most respects except one: Hannibal.

In another mod I did have the game start in 218BC and Hannibal was in the Alps, but he wandered back to Spain. I suspect the AI would do the same with a scripted Hannibal and his army.

So to the question. How could you make this work? Would some scripted rebellions help at all (is that possible)? I'm thinking Mediolanium and Patavium either going rebel, or defecting to Qarthdast might at least prevent a spawned Hannibal bailing for Spain, since there's something to protect.

Then similarly scripted rebellions/defections for Capua and Tarentum, along with some reinforcements for Hannibal later on. How might you then get him to leave once things get bad in Spain?

Can you accurately represent delaying tactics and avoiding battle in the RTW engine?

Really I'm after ideas on how this could be done, or indeed how people have already done it in their games.

Also any thoughts on the composition of a single-stack that could represent Hannibal's army?
