Very neat! The basic idea is similar to the The Hierarchical Taxonomy of Psychopathology

Very neat! The basic idea is similar to the The Hierarchical Taxonomy of Psychopathology
(https://www.hitop-system.org/) — but your model is less convoluted and arguably more intellectually honest, given how little* we actually know about what lies behind these conditions. I can see why those trying to come up with dimensional alternatives to the DSM/ICD systems feel compelled to shoehorn the existing diagnostic labels into their models. But the high reliability of the existing diagnoses doesn't, I think, imply that they are going to fit neatly into a more valid alternative model.
*: To which many in the field would object that we actually know a whole lot — just look at the immense volume of research literature! But the ancients who thought Earth was the centre of the universe also had a lot of empirical knowledge of the heavens and constructed intellectually impressive models to explain it. I can imagine a venerable professor of the pre-Copernican age brushing off a young student's wondering if there might be simpler explanations: "We know this is all really complex and multi-factorial!"
