if you were to make a nietzcian work, you'd start by having your protagonist's growth be learning the distinction between master morality and slave morality, and walking the path of the overman in order to bring a better future for mankind. you'd have the antagonists all represent the ideas of philosophers like socrates, or even schopenhauer and his pessimistic outlook on life, and attack those through the protagonist embodying nietzche's ideals. that would be a true, anti-nihilist work. as nietzche's work is a warning, and a message to mankind for what would happen once "god was dead," and the type of men people would become if they didn't walk the path of the overman. he called them, the "last men."
