Vlad, I see your point. I do like Owen’s line, “Jedi are vermin. I kill Vermin on my farm.” Going back, you could easily cut Reva cutting that woman’s hand. Not saying people should do that, there’s just a lot of ways you could trim the scene.
Omni, if you keep Reva as the person who hired the kidnappers, but cut her scenes on Tatooine, then I think a good introduction would be when she speaks to the kidnappers over hologram, like you suggested. We get enough scenes in Episode 2 that establishes the animosity between her and the other Inquisitors, as well as her motivation to find Kenobi.
I think how much Leia stuff to keep from episode 1 is another thing that depends on runtime. Maybe enough to establish her character and how she was kidnapped.
