damoshe, if there was such a psak, that post-facto such a person is considered a woman to the point that they can marry a man, then I wouldn’t be saying anything. But no such psak exists. The sefer dor tahapuchos is the only posek I know of who weighs in on the issue directly, and says very clearly that according to no opinions can such a person be considered a woman in kiddushin, etc..what he does say is that social halachos, like where to sit in shul, can change, because that person does not look or behave in a way that is intermingling with members of the opposite gender.
There is no such psak ever. Not one. He has no one to rely on, except the heter of rav huna
keivin she’avar, nehesis lo heter. Heter salka daytach? ne’esis lo KE’heter..
