That's more of a architecture issue more than a mod issue. If you ever heard of the game, "Red Faction" you should know it was built with Geo-Mod technoligy, which allowed players to blow up, basically, anything they pleased.
Therefore, I would have to say it will be almost impossible for this to happen. UNLESS, someone makes the ground into breakable glass. You can change the glass to look like sand, so it breaks, hence, a crater.
