Did I miss this ghost Hayden rumor earlier when I was avoiding this thread for the first thirty or so pages, or is that just pure speculation on your part?
No, just my own speculation. I don’t think it would necessarily be a dig at the OOT or a validation of the 2004 version of ROTJ at all. Sebastian Shaw is long gone, and Hayden is someone who played Anakin. It’d maybe be a little silly to make him up to appear like Shaw, but I’d be okay with just not trying to pass him off as 23.
I’d only be truly happy with Force Ghost Anakin if he appeared like ‘god’ in The Final Frontier, cycling through images of Prowse, Shaw, Hayden, and Jones throughout the scene.
A hybrid ghost Anakin concept was considered for TFA.

They could even borrow an idea from 2010, where Dave Bowman’s appearance changed from shot to shot, cycling through his various forms from the end of 2001. And it’s not like they can’t do a CGI Sebastian Shaw at this point.
