a) I think the Lah’mu sequence needs to be reconsidered in light of Andor S1/2. In the original Rogue One, it helps introduce to Krennic. With Andor S2, he’s less in need of an introduction. Further, the sequence breaks Andor’s norm of flashbacks being limited to the narrator’s perspective, as shown in Andor and Kleya’s flashbacks. Additionally, I think Lah’mu should be split into two portions to give the sequence more narrative momentum throughout the episode. I think Lah’mu Flashback Part 1 should begin with Jyn running to her home as Krennic’s shuttle flies overhead, with the following additional modifications:

We exclusively see information that Jyn has access to – we see the ship when she does, we can’t see her parents if she isn’t with them.

When Jyn is packing we hear Lyra making a call and saying “It’s Lyra. It’s happened. He’s come for us.” But we are not shown/told who she is speaking to.

We show Jyn returning to listen in on Galen/Krennic’s conversation earlier, giving us a POV into the interaction

This sequence will end when Lyra is killed and the Death Troopers begin fanning out, with adult Jyn waking up in prison, leaving the audience to wonder what happens in between.

b) After Rings of Kafrene, cut to Bohdi meeting Saw. I think Saw’s band needs less of an introduction after season 2, and we can get straight to the meat of it. It also gives us some breathing room from Cassian/Jyn’s storyline. As a side note, I would keep Bor Gullet, because it shows how far Saw has fallen, directly mirroring imperial torture methods. Plus adding these scenes makes Jyn/Cassian’s story move at a less breakneck pace, because in light of season 2 it feels like Cassian is pinballing around Yavin.

c) After Saw/Bohdi, move to Jyn’s jailbreak.

d) With Yavin featuring so prominently in the show, it requires a less grandiose introduction. We can probably hard cut straight from Jyn getting bodyslammed to her being walked into a rebel interrogation.

e) I think Bail’s presence during the interrogation is pure fan service. In the context of Andor season 2, we just saw this guy, so seeing him again doesn’t add anything to the scene except highlight the awkwardness of the recast, so I think his presence is an easy cut. I think we can also cut the short shot of Cassian undoing Jyn’s bonds.

I agree with many of your notes, but these in particular are probably a smart way to handle things in the opening scenes. In line with my comment about fixing some of the pacing issues coming off of Andor.

On the subject of post-credits sequences, I’m firmly of the belief that the Vader/Leia stuff should be kept to post-credits. It fits with what Andor did in season 1, and it works to keep the main part of the story focused on our actual main characters.

As to the Bix scene. First off, this edit isn’t touching the main series, so it would seem odd to put that at the end of this edit. But even more than that, I think it’s impossible to watch the ending of Andor and not sense that it’s crafted as a series finale, or at least real season finale. That montage of characters at the end, for example. It has the sense of the an ending, but also the beginning of something new. I think in that respect, it’s okay to think of Rogue One, even in this Andor arc edit, to be something more like a sequel miniseries, or like a British style Christmas special, bridging Andor with A New Hope. It doesn’t literally have to be the Andor finale. It’s the story being handed off to Jyn to some degree, before being handed off to the Skywalkers. Which really just fits thematically anyway. In that context, Bix at the end of Andor is the right call.
