I mentioned this in the Resurgence thread for the Shaw ghost, but wouldn’t it be a good idea to do a 3D model of Hayden’s head (with photorealistic textures) to better incorporate the Hayden ghost into ROTJ? Either that or convincingly deepfake Hayden’s head onto a similarly-sized costumed body double (with ROTS-like wig) duplicating Shaw’s expressions.

Ideally you’d do both, but we’re not exactly Corridor Digital.

Really, like hinventon said, the Ascendant Anakin ghost looks great, and it didn’t need any of that fancy stuff.
