Working on Yoda’s Quest now. The original plays out as follows:

Yoda follows Qui-Gon’s guidance to Dagobah
Yoda enters the Dagobah cave, where he sees a vision of future turmoil
Yoda awakens on Dagobah, then sets out for the force planet
On the force planet, Yoda meets the force-emotion people, fights dark Yoda, then has a vision of tranquility, which ends with Dooku striking him
Yoda awakens on the force planet, then sets out for Korriban
On Korriban, Yoda meets an illusion of Darth Bane
CUT AWAY TO Sidious and Dooku discussing an ‘opportunity’ to attack Yoda spiritually
On Korriban, Yoda goes deeper, then is drawn into a spiritual conflict with Sidious and Dooku
Yoda awakens on Korriban, then returns to the Jedi temple

Like with Mortis, I’m not a big fan of being able to materially travel to spiritual locations, so I’d like at least to replace Yoda waking on Dagobah with Yoda waking within the force planet (there’s a perfect shot for this, and it skips his initial discussion with the force-emotion people, while keeping them present and more mysterious).

But then I have two options - Yoda can either awaken from the force planet ‘vision’ (when struck by Dooku) on Dagobah, then fly to Korriban for real, or the Korriban section can remain a vision also.

The advantage of having the Korriban sequence also be part of Yoda’s vision is that I can place the scene of Sidious and Dooku spotting an ‘opportunity’ earlier, so that the ‘tranquility’ Dooku’s strike is what draws him into the Korriban section of his journey. That’d work nicely, as there’s also a useful ‘Yoda opens his eyes on Korriban’ shot.

But the disadvantage there would be the (loose) implication that Sidious can access Yoda when he’s doing spiritual stuff in the Dagobah cave.

Actually, writing that, I’ve realised it’s moot - Sidious needs the Dooku connection (a drop of his blood) to intervene in Yoda’s quest, which he doesn’t have after the Clone Wars. No conflict. I think that’s better.
