So, here’s an idea.
The current version of Order doesn’t restore the “Trelawney during Umbridge’s speech” scenes.
However, I once saw a (much lower quality) fan edit that did in fact restore it.
It combined both the official Umbridge scene with the deleted Trelawney scene, by alternating between the two characters.
From what I remember, it looked decent, and could work in this fan edit.
I could trim out that scene to demonstrate it, if anyone wants to see.
