Well you know the old argument that you cannot unscramble eggs, right? In this case once you decide to live in the public eye, you cannot take it back later.
In my opinion try the quiet life. If after some period of time you don't like it and want to contribute to social causes then do it. But if your name ever appears in a newspaper article or searchable online you can never undo that, or it won't be easy. You know how some journalists like to say, 'Jane smith formerly a man named Robert' means both your old and new names will be Internet searchable for years and years. Who knows what affect that may have on future employment prospects. It may be nothing, it may be everything. Companies these days go so far as viewing people's Facebook pages.
In the end you have to decide are to going through all of this to live a life in a new gender or to make a public statement on gender? I can't answer that for you, you can.
