Any bug like that would either stall the civil war or get Whiterun stuck in siege mode (i would think anyway). It might also have a bad effect on the main story line when it comes to the part involving Dragonsreach. The only definite way to keep Balgruuf in Whiterun is don't join the war at all or to join the Legion.
