Technically your name is also not a name, fox is an animal. (so you should also get a name change)
But for the other guy, if he comes to the assistants he can request a name change.
Also I do not know about the others that do the accepting/declining, but I myself do not memorize every name of every character in every SW game. (also wookieepedia does not have an entry for "Tyberius Zann")
Accually my name follows the X-files char Fox Molder, and since my char is non human, I see nothing wrong as it's techinally a "SW name". And syn, my Sig is W:500XH:90..don't know where you got 500X500

According to wookiepedia, there is two "Fox"s in the Star Wars Universe, one is a name of a ship (Nebulon-B escort frigate) and the second is the nickname of CT-0000/1010 (a clone trooper sergeant in the 501st Legion) So technically it is not a "SW name", just to let you know.
But as someone who approves/declines names, I would decline the name Fox. (tell you the truth, I would also decline my own name as well, but that really does not matter eh)
