You have already been advised of the medical reasons why such a procedure would be inadvisable. I wont go on any more about that other than to reinforce that the risk of medical complications is significant.
I suspect that the reason that you copped it from the TS forum is that those who are TS go through hell and beyond dealing with and addressing their gender dysphoria on multiple levels including psychological, emotionally as well as physically. The way you are describing this it does come across that you think it would be nice to have a bit of a cosmetic "nip and tuck" so to speak and this belittles everything that a TS individual goes through. I think if you look at it from this approach you may better understand their ire.
Personally I think you need to try and understand your desire for such a procedure. Do you wish to live as a woman full time? Do you also want breast implants and all that entails (far more difficult to conceal or hide that socially)? Does the idea of having a vagina have an arousing effect for you, or as someone else pointed out, do you have sexual fantasies about being having sex as a woman? Do you wish to be on HRT? Or do you have a body dysmorphia (i.e. desire to remove apparently physiologically normal body parts)?
I think you need to think about these questions, preferably with the help of a professional counsellor, before worrying about whether such a procedure exists.
Perhaps you could consider trying one of the prosthetic "vaginas". There are a few out there, I believe there may even be some members here who have tried them (Docrobsherry certainly comes to mind) who may be able to help you.
