Also, and this is a related idea from the Radical Redux Thread, but when Rey is showing Leia the Wayfinder illustration she says ‘There are cyphers here I can’t read’, which may be an opportunity to show an illustration or two of the Sith Throne and the legends of its power to revive dead Sith. This would again be a rough little set of drawings placed on the page right before the Wayfinder page which would need to be vague, but if we see the shape of the Sith throne and some symbols it could go a long way to suggesting that the Throne was what allowed Palpatine to be revived and that destroying it would lend more finality to his defeat.

Of course, this idea doesn’t preclude any other interpretations of the final confrontation or require any other changes to the film.
