William Golding's potential decisions: What about girls?

If girls had been included in the children stranded on the island in Lord of the Flies, W.G. would have to make a many different decisions. He could have decided to make the children older, and add some sort of romance? The girls could be tough, or turn tough, because of all the ruckus caused by the boys. Or perhaps the girls could be frail and weak, protected by the strong boy-men. The boys also could not really run around naked, as they did in the book. That would be pretty awkward. The girls could be gatherers, and be the ones watching the fire, so that all or most of the boys could hunt. There could be less conflict if there were girls (less conflict about hunting?), or, on the other end, more conflict (girl-fights and fights over girls?).
