I agree overall with your economic analysis, just one thing to point out:
You might be able to get _some_ economies of scale if you homebrew your own adventure and reuse it with multiple groups.
In terms of other ways to scale your per session income is to allow people to just watch the sessions you're DMing(a la Crit Role), but at this point you're a content producer (not to mention the players might not like being watched by others).
