I really appreciate the way you’ve incorporated the Ahsoka TotJ episodes, and I thoroughly enjoyed your new interlude; I honestly couldn’t work out how to fit all that together chronologically, but you’ve nailed it in my opinion. My only comment on the interlude itself would be that the “Imposter Inside” and “Teach You I Will” FoD episodes feel out of order. I appreciate they’re presented in the same order as the series, but in “Imposter Inside” Ahsoka seems familiar and comfortable with twin blades, whereas in her training it’s implied she’s only just received the second lightsaber. That said, it works well in the transition to her Clone training with twin blades in the next scene, so I guess there’s arguments both ways.
I typically watch RotS using a Siege of Mandalore cut, and so skip your episodes of that arc (sorry), but I’ve yet to find one that incorporates Ahsoka’s attendance at Padme’s funeral without adding a ton of game cinematics or episode 1 of Bad Batch (I feel that sits better in a standalone Bad Batch edit), so doing the other Ahsoka TotJ episodes as you advise works as a solution also. Even if I did find, or even make (that’d be a learning curve) my “perfect” cut of RotS, I’d still have a standalone short episode of the rest of Resolve to fit in afterwards.
I agree that the first two Dooku episodes sit well as a standalone pieces, although I did find an edit of TPM that included the final episode, much like how I enjoy SoM being included in RotS.
