I highly doubt that as all of Olympus would blow up since Hera is the goddess of marriage and family. Imagine what Zeus would do, that would just shut off the whole of Olympus again and make the quest impossible especially without Hera's help.

And I don't think he would introduce a whole new character to be one of the 7 in the third book when we're so far into the story. (I know everyone says Rachel Dare but she's the Oracle and more of an inbetween of a primary/secondary character, and she's a mortal.)
