I was thinking something like Leia opens already in the tree with Lola observing the ships, Breha comes to get her and we have the scene where Leia and her cousin have the disagreement, she runs out and gets kidnapped. Bail’s first major scene then ends up being where he’s in Kenobi’s cave.
This is off the top of my head and I have no idea how well it would work in practice but it could potentially streamline the alderaan/leia kidnapping stuff.
