I’ve tried to repitch Hayden’s voice before with the ElevenLabs tool that takes existing speech dialogue and basically applies a filter over it. In this case, the filter was a chunk of his dialogue from the beginning of AoTC. It worked great - except when there were lightsaber noises in the flashback scene. As far as I’m aware, it isn’t possible to separate those noises from the speech in the audio track. So in order for this to be possible, his dialogue would have to be generated completely from scratch and all of the scene’s audio tracks entirely remade (would take a ton of time and effort).
