You must not have worked for a project that has legions of people looking to rules lawyer and nitpick their way into being right, have you? The rules on this are pretty vague for a reason but anyone taking a moment to think on it will realize how deliberate you have to be to make a character that gets generic'd. The devs and GMs have better things to do with their time than making a list to satisfy the small handful of people who purposefully skirt the line to find a holy grail of 'being' Batman without getting hit with the bat.
Be original, it's not hard.
