That was sort of my train of thought as well.
Maybe instead of using any radio shots, you could just have Kylo looking up, the eye close up, etc., and a shorter line from Palpatine. Just a brief, “Find me…” that could sounds like a whisper in the wind.
Again, this isn’t against the work you’ve already done. I think it looks great. This is just constructive criticism on the idea in general!
