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.

I may just be spitballing here, but a well-produced Hayden ghost would be my preferred version of Anakin. I’d say we’re at the point where it would be doable.
