First, the gender question. It is a non-issue. Ignore it. The parents will, too.
Second, the age range. If you play to the fives, you will lose the over sevens. If you play to the 13s (essentially adults) you will lose the under tens. But the fives will keep up with anything pitched at nine or ten years, so they will not be a problem. They will follow enough to enjoy it. The problem will be getting the older teens on board.
I normally begin by doing something quick to show the 13s that they will get something from the show, then I subtly get them on side, by letting them know we have to keep the younger kids entertained, but if they stick go along with you they will still enjoy themselves. Then I pitch the show at around ten years age. Girls are slightly more caring about younger companions than boys (a gross generalization I know, but slightly true), so they will probably get on board, and it will be a successful show. But plenty of laughs - kids love funny.
