Just something to get nearby guards to help out if they don't automatically, maybe from a larger but realistic area than they normally do. Imperial/Stormcloak Soldiers too, if near them (careful if you've taken a side), as well as the Companions and any other groups or individuals that would make sense, if possible. Options could be either having them automatically aggro on whatever enemies are hostile to you, or if that might cause problems with them taking your side when they really shouldn't, maybe just call them to your locations and let them aggro like normal. Perhaps adding a horn item that would enlarge the radius of the call could be possible, too. Kind of surprised if one doesn't already exist, but haven't seen anything ported to SSE yet.
