I’d vote for either leaving it alone, or just trimming it a bit to be less goofy. I don’t really see what benefit would be gained from adding new material to make his death more definitive somehow, besides having the edit be explicitly incompatible with both extended universe canons. As far as ROTJ has ever been concerned, Boba isn’t getting back out of that pit. Drawing more attention to it might even wind up achieving the opposite of the intended effect by reminding the audience of his various EU survivals.

Admittedly, I’d change my mind in an instant if Adywan did something super impressive for it, though, haha.

An optional second audio track that replaces the “What the!” and scream with some appropriate, less silly Temuera Morrison vocalisations (e.g. from the Battlefront games) would be neat, though perhaps not really the direction Revisited tends to go in.
