It's possible but I really don't think it's a good idea, One of the most interesting aspects of the original films is the time period in which they are set.
HIS CHARACTER WAS ORIGINALLY IN THE SCRIPT WITH A SMALL SCENE, BUT THAT WAS REWRITTEN TO USE ANOTHER CHARACTER IN HIS STEAD. HE WAS FLATTERED TO BE ASKED TO REPRISE HIS ROLE, BUT HE'S STICKING WITH RETIREMENT.
I wonder if the film will still make reference to the character at all?
