I personally don't think it's a good idea because first of all you are changing your identity second and the most important point is that you have already mention about your education documents and all other documents on which your name is mentioned, things seems easy on local level but by any chance if you need to move internationally you need to prove yourself at every checkpoint and believe me it will be a huge disaster for you.
I hope you understand the point but this is just my opinion rest is up to you.

I hope your decision will be the one that makes your life easier and satisfactory.
