Just had an idea while watching Classic Game Room's review of Warriors Orochi 2 for PSP. About halfway through, there is a loading or character select screen with a girl holding a shield and rapier. However, at a glance, her pose made it look like she was holding a violin and a bow.
Idea: Fighting game character who uses a violin and bow as a weapon. Her bow acts like a sword (mostly for poking) and her violin has razor sharp metal strings. I see one of her throws involving knocking her opponent to his knees, grabbing him by the back of the head, and then her violin string-side across his face. It would produce a discordant noise and leave four parallel gashes that rain blood down his chin. A finishing move would be similar but she would run her bow across his neck and leave him to bleed out in the sand. Obviously, she would also play her violin during the fight (maybe it should be a fiddle?), as a taunt, a special attack, and a victory animation.
