While I do understand your reasons for removing the scene, I am in favor of reinstating it.
In addition to the allusion you mentioned regarding the screams, I also think the scene serves to show the depth of Anakin’s fall to evil. There is a similar heinous act of evil committed by the primary antagonist in TFA, which shows a similar detachment from humanity by way of unconscionable violence (I’m intentionally being vague). This parallel I think is a strong one, and merits keeping the scene in ep4.
The modified presentation you outlined seems like a good compromise.
That’s just my two cents though. I’d be curious to hear others’ thoughts.
