I really want Sebastian Shaw to morph into Hayden Christensen - but not the same shot of Christensen that was used for the DVD/Blu-Ray release.
Heck - morph Alec into Ewan…Yoda can stay the same.
Why must Yoda stay the same? Yoda passed away before the Prequels were shot but they had a nice recast followed by a CGI reconstruction. Have him morph from puppet to CGI.
