Yes, and completely rearanging your atoms couldnt do that could it!
Its sci-fi people, normal rules dont apply otherwise the tardis is fucked!

sci-fi always must maintain an internal consistency. when the writers disregard that they risk alienating fans and turning the show into a joke.

And changing how The Doctor looks and sounds is inconsistant how?

a gender change is totally different. with the past regenerations it's still the same basic stuff being altered.
I'm sure they could do it and give some explanation, but I think it'd be stupid to switch genders. It would have to be handled perfectly without a single misstep. And the female doctor would have to be played by an incredible actress who can be funny and smart and pull off gender confusion.
So yeah they could do it, but it could destroy the franchise and possibly the world.

Bow ties are coool.
