As an spanish speaker.. II can say that nova indeed sounds as no va.. but you really must make a joke about it. I doubt noone would not buy it for the name.It does nto sound bad to me.. you ahve to STRESS the joke. So, unless it becomes some kind of national joke because of TV influence (or a smart-dirt campaign of the competition) it would have no problem.. in Spain at least.

A pleasure
