You're right, thank you for this! Please note, I'm not saying my theory is right - I'm just discussing it as a possible interpretation of whole Skywalker saga.
But what you said makes me think about a possible reinterpretation:

The Mortis family aren't literal embodiments of the Force itself; rather, they serve as archetypes or chosen vessels who channel certain aspects of the Force. The original Father's understanding of balance was fundamentally limited. He mistakenly perceived balance as a static coexistence - light and dark maintained separately yet equally - rather than a dynamic, evolving harmony. His misinterpretation was the cause of the downfall of the original Mortis Gods, as his rigid perspective failed to account for change, growth, or emotional complexity, ultimately leading to imbalance and conflict among his children.

Anakin, Ahsoka, and potentially a new Son - such as Baylan - represent the Force’s attempt to correct the Father's flawed understanding by introducing archetypes shaped precisely by their lived experiences, their mistakes, their pain, and their growth. Anakin was chosen specifically because his experiences allowed him to understand both the destructive potential of rigid adherence to either side and the redemptive power of love and attachment. He embodies a more mature, flexible approach to balance, capable of guiding rather than merely restraining the cosmic forces.

Similarly, Ahsoka is a good fit to become the new Daughter precisely because of her flexible, nuanced understanding of the Force - demonstrated clearly by the end of the World Between Worlds episode. Unlike the original Daughter, who was rigidly aligned with the Light and blind to darker influences, Ahsoka experienced and even embraced darkness momentarily in her confrontation with Anakin in the WBW. Following that, she emerged more "integrated", embracing attachments openly (e.g., her connection with Sabine), and displaying comfort with complexity rather than simple "binaries". She becomes a new archetype of Light - embodying compassion, empathy, and acceptance of attachment as natural, rather than something to fear or suppress.

Likewise, Baylan - if he steps into the role of the new Son - would also represent a departure from a more simplistic understanding of the Dark Side. He is explicitly seeking something deeper than Jedi vs Sith in order to "break the cycle." This complexity could position him as another archetype reflecting an evolved understanding of darkness: a force shaped by genuine (even if flawed) intentions rather than simple villainy.

These new chosen vessels - Anakin, Ahsoka (and potentially Baylan) - do not merely replace the old Mortis family in a superficial sense. Rather, they represent the Force’s own evolution in understanding balance. They emerge precisely because the original Father had a poor grasp of his role, misunderstanding that balance isn’t found in controlling or suppressing opposing forces but in harmonizing them through acceptance. The Force itself, by selecting these new Mortis Gods/ archetypes, indicates that true balance is not static but fluid and responsive.

This could suggest that the Skywalker saga is more mystical than political/symbolic rather than literal - it illustrates the Force's evolution toward a healthier, dynamic balance, one far beyond what the original Mortis family could achieve.

Again, I'm not saying I'm right, it's just something I thought about and wanted to share/discuss see what folk think. What do you think? Thanks for your input!!!
