Can the ghost be accompanied by other ghostly manifestations?

Curufin is going to be visited by his cousin Finrod, whom he tricked and sent to his death. Since Finrod was killed by a werewolf who was one of a pack, could he be accompanied by ghostly werewolves, as symbols of the pain of betrayal?

They wouldn't have the power to attack Curufin, only to prowl around and metaphorically suggest that Curufin was a wolf in sheep's clothing at the time he screwed Finrod out of his kingdom.
