Right at the end of AOTC there are a couple of seconds of footage of Bail on a balcony dropping his head and striking his fist on the rail in defeat.
It’s a sunset scene with red lighting and so it would be perfect to repurpose as the moment when he sees the apocalyptic destruction wave roll across Alderaan towards him. It also has the classic iconography of a King on their balcony surveying their Kingdom, so even first time viewers ought to be able to make the implied connection that this Royal-looking person is Princess Leia’s father.
PT:R is no longer happening so no harm to pinch a snippet of footage to repurpose. The dignified character meeting their doom like a man is a classic movie trope. Small moments like these can pack a big emotional impact.
