I think that "it might be no different to the Doctor" is fair, as is "it might be different".
My own feeling is that it would make a difference to the Doctor. Here's why: gender for Time Lords seems to work pretty similarly to how gender works for us. There are two acknowledged sexes and two genders, and for most people, their gender matches their sex. This seems to continue across regenerations, since every Time Lord and Time Lady we've seen, and almost all we've heard about, has kept the same sex and gender each time. The Doctor will soon have regenerated eleven times, almost a full Time Lord lifespan, and each time he's stayed a man. This suggests to me that being a man is important to him.
A good fic could certainly convince me otherwise for the duration of the fic, but as an interpretation of "what's really happening in canon," I don't see gender fluidity in the Doctor.
changing sex without changing gender could be cool
Well, it could be interesting. Do Time Lords use technology to deal with non-matches between sex and gender identity? Or, given that biology for the Time Lords seems to be a fraught and taboo-ridden subject, is it discouraged or culturally forbidden and people are just supposed to wait for their next regeneration?
I don't think I could read fic about a transgender Doctor if he wasn't able to do anything about it. It would be too personal and too painful.
