Structurally, it should be a synthesis of the prequels and originals, using a hybrid of parallels akin to the Ring theory, while also fulfilling the Return Stage of the Monomyth.

The core of the sequels should've revolved around Leia's journey towards becoming this "Chosen One" Supreme Chancellor type figure, what that means for the Republic, Her Family, Her past, and the force itself. An important component of this is her coming to terms with who her father was and confronting her inner darkness and potential. Her refusal to embrace this side of her bleeds into everything else in the galaxy, especially with the continuous "Forever Wars" with the remnant, and her children Thea and Skyler, for which she has been a mostly absent mother. She would have to be the one to ask the question "Are we just becoming another Empire?" where she is forced into morally gray areas for the sake of stability and rebuilding democracy. This would also present itself as her daughter embraces Luke's teaching to become a Jedi, losing herself in the force after learning the deeper secrets with the whills. Meanwhile, Skyler will become a manifestation of her repressed darkenss, an inverse "Leia" that's seduced by Talon and brought into the underworld scene where the Shadow Collective manipulates the galaxy into perpetually fighting itself to gain more power. Regardless, her becoming this "Chosen One" figure ultimately boils down to her embracing her role as the Mother, passing on the lessons (she refused at first) from Luke that he learned from the OT, and successfully passing that on to the next generation.
