Possibly there will be as Peter Capaldi's :
resemblance to Caecilius and John Frobisher (the human not the shape shifting penguin) aren't going to be ignored.
Romana 2 (the one that claimed she could fly) looks like Princess Astra because she liked the look.
Perhaps Doctor 2 looked like Salamander so the Tardis could be in a position to do what she does to him (she has a hand in the renewal process and can see the future).
