I agree with your overall schema, but there is an exception in the case of the flat (non-changing) protagonist. Not all flat protagonists are already self-actualized. "Not changing" can in fact be the point, if the main character "needs" to change (in order to conform to the audience's sense of propriety or normalcy) but doesn't. The audience may want the protagonist to change, but the static outcome frustrates this expectation, e.g. the Mike Leigh film "Naked" or "Medea" by Euripides.
