I had a pretty strong idea of the traits of the various aliens. I knew the Cara’ot were master traders, and genetic engineers. I knew the Isanjo were functionally high steel workers, the Flutes are highly skilled in mathematics. Truthfully I cheated a bit though I’m going to have to address this in book four since I have an alien view point character. Because the aliens are a conquered people their own religions, cultural norms, etc. have been suppressed by their human rulers. Most of them claim to worship human gods, particularly the Christian god, they don’t have to accept the limits female participation in business because they are considered less than, but in most ways they try to ape their conquerors. It’s just safer that way.
You present a persuasive argument for the abandonment of the 5-paragraph essay and suggest a new format for presenting an argument... However, you did not provide much information on what is expected to go in between your introduction and conclusion? You suggested this format opens the essay to compare/contrast, cause/effect, analysis, etc... but how do you suggest students structure an essay with these approaches in practice? Any piece of writing needs some structure and main ideas that are then supported with various pieces of evidence (whether you are writing a historical thesis or a persuasive essay)... If you are abandoning a "main idea followed by supporting evidence" format, what do you propose should take its place? Or perhaps my understanding of the 5-paragraph essay you are speaking of is incorrect?
