Besides the fact that you haven't listed the actual surname or given it a reason for WHY it sucks (unless you were trying to imply a poor parent/child relationship), the fact that you want to rename yourself to Nikola Tesla comes across as either some creepy tribute or a self-absorbed cry for attention.
Think about it. For the sake of argument, let's say you actually did change your name to Nikola Tesla. How many people do you think will actually get the reference (I, for one, first heard of the guy only after playing Fallout 3)? For those who do, however, what do you think would happen if people realized that you had your name deliberately changed to that? I can understand when parents give their children such names, but changing it yourself might earn you even more flak.
