We tried to keep on eye Vore situation, atleast i was aware that Vore could be one to be sieged at some point. I had prepared it with keeping good amounts of gold and hours all the time so i could have recruited additional militia.
I would guess, you could have attacked there, but would have been driven out in few turns without causing too much damage...
We would have seen you coming pretty early and travel times for big army would have been pretty high. So total suprise attack to Vore would have been hard. We scouted border all the time.
