Nah, the LUTs already in use are better, if I remember right.
Here’s two clips. The finished puppet show and conference room (complete with “Captain Hux”).
That puppet show looked flawless to me, even in fullscreen. Wouldn’t think twice about it if I’d never seen the film. I love the design of the AT-M6 too, making it look like an animal.
‘Captain Hux’ sounds reeaally close to perfect, but there is a noticeable splice. If ‘Captain’ could be made to inflect more down in pitch at the end it could sound more natural.
