Oh... I didn't even see that the ninja was similar. I also like Strider's suggestion. Godmother: "Can choose who she 'visits' aside from the kill that mafia selects." So, in saying that, she won't be detected in the kill, but she can choose to visit someone else to look like another role, OR choose to visit no one.
Change to "-Appears to visit someone else else she chooses", so in games that have a ton of visiting roles she can "visit" people who are recieving guns, etc?
