Is there any way to make battles more strategically decisive?

Back to the topic for just a second:

What if there was a trait, "Losing the War" that all family members of faction x get if they lose 3 or 4 large battles in a row, with massive negative affects for moral, tax income, bribability etc. For balance there'd have to be some way to reverse fortune, I suppose.

Another tack would be for a faction to have a counterpart to victory conditions, i.e. failure conditions. Let's say for example SPQR is driven out of Rome and/or Italy all together- script gives them x number of turns to get back before killing off all their family members. Something along those lines.

If there only was a way to make the AI accept and honour peace, war weariness would be a good concept to implement, affected by battles/sieges/war length etc. There isn't .
