Wow. That. Actually makes a lot of sense. Zoe was made as a continuation of, well, Zoe. The concept is really no weirder than there being a comic book in which she's a character. It also sounds like the work of sentimental and well connected parents, to Sharon. Like Walt Disney's frozen head...

"Well you're very talented on Caprica, Zoe. We're probably a century away from independent artificial life. And I'm sure it won't dress half as well as you."
