If you’re planning to keep some amount of ‘the Jedi have lost their way’ as it appears in the PT, then Yoda could already be distanced from the Order because of this. I’d have him already isolated somewhere, personally. Mentioned but unseen until Empire.

I’ve long felt that episodes 1-3 should do all they can to preserve the secrets and twists of the original trilogy. It’s the only way to make watching them in numerical order satisfying. Some bits would be harder than others, but I think it would be worth it. Belated Media did a PT rewrite series that had some nice ideas in this vein.
