If you haven’t already, you might find it interesting to read Christine Korsgaard’s Self-Constitution. She’s basically trying to answer the “why be moral” question from the Republic, using a combination of resources from Plato, Aristotle, and Kant, and the one-line idea is that acting rightly means acting in ways that constitute yourself as a unified agent. She wants this to mean that the agent boundary pretty much lines up with our ordinary idea of persons, but I kind of think her argument in Ch. 9 where she links self-constitution with morality ends up leading to a kind of single rational super-agent which every rational agent is a facet or tendril of. Hoping to write a review of this book at some point.
