If YOU script it, it's possible.
But still, for now i'd rather stick on feasible stuff.
Moghuls = Good.
Rockets = Bad.
(still, it's a cool idea).
Another thing that CAN be done (and i want to try it, dammit), it's destroyable props.
There are already in warband, but i think that expand it to, for example castle gates, or wooden premises, to be taken out with a hand cannon, would be just great.
I mean, the cannons are there for a reason.
What do you think?
