Yay model building and experimenting!
I like, and would love to see more of, people building simple models to experiment with the plausibility of ideas and build intuition. You also seem to have approached this with a good epistemic attitude; yes, this does not constitute strong evidence that humans are implemented with sub agents, but does demonstrate that familiar humany behaviours can arise from some form of sub agents.
