this is a very good idea. i myself have wished that that feature were included in morrowind. but in oblivion, it not only has a good use but it could also be quite fun. imagine sneaking behind a guard on top of a guard tower. you attempt to take him out as quickly as possible but it ends up taking you a lot more time not to mention makes more noise than you hoped. so what do u do w/ the guard at street level shouting at you to cease your actions and come peacefully blah blah blah.....you chuck the body of his fallen comrade at him.
i don't know about everybody else but it sounds quite fun to me.
