I've seen that theory before... My avatar use to be nine smileys, positioned in a way very similar to yours, Eric. I originally made the picture as a test to see which face people would assign each Enneagram type to.
And if I understood you correctly, you were calling for each variable to be scored in a stack as was I. Interesting.
Also, I too observed independently that one aspect of the Enneagram was akin to Horney's three styles. This was the foundation for my Aggressive, Supportive, Evasive trichotomy. Don't that beat all?
However, I don't think any adjustment really salvages the wing system, because what I have uncovered is that the wing system has a totally illogical basis. It's more aesthetic than practical.
