I like the scene but you’d have to cut some of the banter between Grievous and Anakin/Kenobi when they get captured.

“You’re shorter than I expected!”
“What? Did you already forget what I looked like from fifteen minutes ago when I executed Shaak Ti?”

It also obviously precludes you from implementing the scene where Anakin kills Shaak Ti. That scene does have the problem of suggesting Shaak Ti doesn’t sense any of Order 66 going on around her, though, and requires some not insignificant AE work to clean it up.
