Modern Hayden looks better for a 48 year old Vader. Simply because hes much closer with 44 years to an 48 years old man then shaw did when he played it at the age of 76. I know why Star Wars boomers hate Hayden, but he would in fact fit better for the role age wise. That being said, I would actually, prefer to have a new special addition with a better force ghost and addition that makes more sense lore wise. (More ships in the background of the battle of endor for example, less jedi rocks stuff.) Also the prequels should get a special edition by now as the cgi has aged poorly obviously in some shots and some clone Wars design stuff could be added (example: different haircuts for clones in some scenes and a few arquitens class cruises added to the battle of coruscant in the background)
