I find it do funny when kids phonetically spell out non-romance/non-Germanic languages. Just makes em look like they talk gibberish. I remember seeing an entire thread that consisted of two kids talking back and forth in phonetic russian. I later used google translate to see what they were trying to say, it turned out to be a boring topic.
On topic:
Dude, just go with a simple name that everyone can say easily, if they can actually say it. Also, don't do phonetic non-romance languages, please. Just makes you seem like a cigarette.
I do want to know why you decided to use ancient Greek, and not new testament Greek, or modern Greek, απότομηπάγο νύχισκιά (apotomehpaio nukhiskia) sounds much better, but not really.
