I always imagined right before Madine dies the shot becomes green, if you know what I mean (rhyme by the way). Like as he's saying something a green filter fades in to represent the DSII laser fire, then the ship explodes.

As for the Vader vs. Jerjerrod scene, if we can dub it that's perfect, but otherwise I think it could work without a line from Vader at all (Jerjerrod says Vader can't see the Emperor, Vader chokes Jerjerrod, Jerjerrod changes his mind).

The green filter might just work good idea....

I think you could be right about the choke scene too, just have some Vader Breath then cut straight to the throne room. But also if the dub could be done and sound like the real thing or string a few exiting words together to make it work but may not need it as you say.
