I'm not so sure "right" is the right frame here. I like the multi-dimensional viewpoint you take. My experience would be a healthy personality would be one capable of adaptation in service of your interests at any times. It's dynamic.
This reminds me of Bob Kegan's stage of adult development. Initially, most of us leave adolescence at the "socialized" stage of development, ie our personality basin has primarily been determined by the external factors of our upbringing and environment.
From there, if we choose to continue developing, we eventually reach a "self-authored" mind, where we have transcended our socialized basin in favor of a self-defined and created personality structure, until ultimately, for those who continue evolving, we reach a "self-transforming" mind, or a mind capable of transforming itself.
I like the simplicity of the model, and I also think it reduces personality to an unnecessarily static entity. Things like internal family system/parts work also demonstrate that our personality is not a singular entity, it is represented by a whole slew of parts that show up in different ways and different contexts! I think the broad strokes of it still hold, and also think there are many additional approaches to truth and the awakening path, lying in parts work, embodied transformation, and whole bunch of other experimental modalities (thought perhaps that's just my personality speaking...)
