Maybe you could somehow create an force vision for Luke on TJL shpwing some bits like Rey training, resistance winning the battle, Rey Killing Kylo etc.
BTW, i like the idea of the duology with TLJs open ending.
You could still use Episodes though in my opinion. Maybe you could use T Zahn titles as a nod 😄 lets Say, “the spectre of the past” and “the vision of the future” 😉
