Destruction Paint Tool

To add to the ruined walls windows and items there should be a paint tool. The purpose would be to make a room that is in the process of being destroyed and you only want one wall or a corner beaten up. With the tool you can create the line of destruction a catapult would make on a town. Maybe with the help of AI you could make different types of destruction; Fire, Time, Projectile, earthquake… ect ect. For stuff like projectile you would click and drag the angle and velocity of an object and what ever it hits would alter the state of the wall or item. I think it would also be cool if different items were effected differently. Tables and dressers are knocked out of the way while smaller objects just smash into lots of pieces. Anything from this list of hopefully not too impossible ideas would be awesome, great stuff for battle maps and sieging castles specifically.
