Yeah, it might look cool, but (a) it is impossible to do in OFP, and (b) I'd rather have about 1 million more important physics improvements in OFP2 before this one. Besides, OFP isn't like most corridor-based FPS, where you are like 20 feet away from guys you kill. In OFP you are usually hundreds of yards away, so it isn't that noticable anyway.
