Josh is Moriarty: sleek, evil, psycho, wildly destructive, soooo changeable, and not averse to drawing a little blood.

While Dickens is fat as the classic Conan Doyle version of Mycroft, his personality is more John: ridiculously tolerant, comfort-loving, reserved, and able to fall asleep anywhere. I also caught him rubbing his face lovingly against the Sherlock badge on my bag (featuring Benedict Cumberbatch's face and the phrase "Brainy is the new sexy"), so clearly he's keen on Sherlock.
Nikki would be Mycroft: quietly watchful, icily disdainful, and with a deep-set hatred of Jinx, who loves to torment her with his antics.
Anna, we're all going to miss your wit and creativity.
