Can't see James Nesbitt as the Doctor - I wouldn't believe he was superbly intelligent like Who.
I originally believed that the Dr became younger with each regeneration - starting out as a pretty old man, and gradually getting younger - this would pose him some difficulties when he starts regenerating as a twelve year old, but it would be a consequence of him being so careless with his past incarnations. This rule no longer seems to apply, so there doesn't seem to be any particular logic behind how he regenerates, or if there is, it's a logic that lies beyond human comprehension.
In this case, I can't see any reason why the Doctor should not regenerate in female form. We have women bishops now, so why not women time lords? She could find herself a young male companion for the show.
