Crazy how time flies, huh? I got Kona in 1997 when I was living in Oregon, and my friend's un-neutered female got out. She was a Tortiseshell with one eye and a stubby tail (part Manx?), and we think she mated with a feral Siamese, resulting in 5 kittens... one was stillborn unfortunately, then there was a white male with gray spots, 2 tabby/tortie girls, and the all-white Kona. I originally picked the spotted boy, but changed my mind when Kona started developing her points. I love Siamese cats, and knew she was getting the markings of one. Think I'll go with your idea, and call her a Piebald from now on.
They both do resemble Snowshoes and Ragdolls (minus the long hair), though...
