The buzzer and the LEDs are both great ideas that would never have crossed my mind. I agree, the stalk switch would not look right. I remember in the 1950s older cars in the US had a clamp-on stalk system added by the owner if the car had no turn signals from the factory. I'll bet the J.C. Whitney catalog still has them listed.
Tommorow I'll look for suitable LEDs.
