lord of the flies and plato's republic

I am a teacher in a school for profoundly gifted kids and have decided to use this amazing novel in my philosophy class. The dominant text is Plato's Republlic and I hope to enliven the students' experience of this text via a juxtaposition with the novel. I have never paired these two before and while I am very familiar with Plato it has been many years since I thought about Lord of the Flies. I could use any advice about resources, ideas, hooks, lesson plans, projects....really anything that might make this better for my students.
