Why not film new scenes to make the Prequels better.
Liam Neeson, Ray Park, Ian McDiarmid can return to film new scenes. While Jake Lloyd, Natalie Portman, Hayden Christensen and Ewan McGregor can not, due to their ages, and Christopher Lee has passed on.
So why not fill in some plot holes, make some new ones 😃 and try and make them better. I know it won’t happen, I mean, you could do something like this, but all parties (Disney, George Lucas, Kathleen Kennedy and the actors) involved would never do it. They do have the ability to do it.
It is what it is, and that’s all you get.
