So back in my old TTT Community, we used to have a rather amusing/useful T weapon called the "Masterkey". It's essentially a door breaching shotgun that when shot into a door, flings it open killing anyone in the door's path. (essentially it converted the door into a prop and just prop killed in it's path.) It was custom to that server so no link but perhaps it could be re-scripted? It would be a good way to combat door spammers as a traitor if you used up a harpoon.
