Naming the tenth planet

Although my childhood fascination for astronomy has waned over the decades, I have a moderate interest in proposals for naming the tenth planet, 2003 UB313, which is larger than the ninth planet, Pluto. My own suggestion is that asteroid 399 be renamed and Persephone be given to this "new" body in the solar system. Think of what this will do for the field of pop psychology: "Men are from Pluto, women are from Persephone." It has a nice ring to it, don't you think?
