I get the Will & Kate thing, but do you have to nick name her Kate? I have a friend with that name that gets called Cassie. What about Kathy as a NN?

Otherwise, I would go Jessica Jane & just forget about the whole porn star thing. That particular one should be long gone by the time your DD is old enough to know what a porn star is. And another could pop up with whatever name you end up picking anyway.

Out of the other names you've listed, I like Emma, Amy & Zoe.
