Is the form of a classic Doctor? It seems like such a Master thing to do. Mock the Doctor by taking his form. Imagine the Master setting his TARDIS to look like a blue box and then sauntering off to perform all sorts of heinous deeds, all while bearing the face of the Doctor.
They could do it using a current Doctor, playing for two, just like when Smith played that Cyberman thing. They could also use it as a way to bring back an actor who played a previous incarnation. Imagine the Doctor having to chase down a maniacal Davidson, McCoy or Tennant (IMHO those being the actors most likely to go for something like this).
