As a matter of fact the issue is not really Chewie walking past Leia but more Leia hugging someone she doesn’t know (and someone we know thanks to TLJ she really never met before ! They still have their scene together when Rey leaves to Jakku, so removing it wouldn’t damage the narrative flow in any way). I believe cutting the scene to go straight from the Falcon arriving to the “mourning situation room” would fix all issues regarding Chewie. But it’s such an unpopular opinion I might be the only one to wish it 😄

As far the Rathgar sequence, you should check out DigMod edit which almost nailed it by also removing the “Han using Chewie’s blaster” joke (I just remember it was a little bit too dry and that a few shots should be reinstalled).

Since you wish to deal with Finn and Poe escape, DigMod also removed a few things that make the entire escape feel more serious (or less like a comedy):

he removed Poe and Finn’s conversation after Finn says “Because it’s the right thing to do”
he Removed Finn firing on and killing Stormtroopers and the traffic control room (but you already intend to do so)

And, à la TLJ:L, I believe it would be nice to cut down a little bit of the over the top humor that is something quite embarrassing, such as (more or less exhaustive list based on DigMod edit… and I know most of it would be an unpopular removal but in case people would have changed their mind about some parts of TFA now…) :

Poe’s “so who talks first…” lines and the mask joke (I agree it’s sort of funny but he’s the main vilain who just butchered an old guy and killed many villagers, making fun of him right now seems very out of place)
Finn and Rey’s excessive teenage celebration after they make it to space (yeah it’s cute but a little bit long, DigMod cut it down and made it work better in his edit)
Finn’s line “you got a boy friend?”
Finn childishly pushing down on Rey’s head
Han’s no look shot and use of Chewbacca’s crossbow and subsequent “I like this” line
troopers walking away from Ren’s wrath after he discovers Rey is missing
Han’s “so it’s big” line
Finn’s “I’m in charge now !” (it would go like this: “Remember me ? FN2087 – Not anymore. Follow me”)
Finn’s lines about not being ready and his head nod “what’s that” lines when he doesn’t understand Han shows him to look behind

There also is a very nice deleted scene that could be reinstalled if the quality permits it (the Kylo visits the Falcon deleted scene).

And, the ANH forced references (Han’s 14 parsecs reference, Luke’s training sphere out of the blue, trash compactor reference with Phasma… I’m OK with the chess game 'cause it looks nice and it’s the Falcon so it works in a way).

About the restructuration itself of the plot, i’ll need to think things through with pros and cons. I really like v2 version though.
