Since it's already done before as you know it, the possibility should be open to anyone I guess. Sure we don't want to see everyone doing that, otherwise it will be like a mess. Though some actor or actress who participated MCU before you might find they deserve a 2nd role. Me go first.
Hiroyuki Sanada had a small role in Endgame which is so small that I feel it's kind of a waste. I think he can use a 2nd chance to play another character, someone more famous and more important. I know he also had played a character in the non-MCU movie The Wolverine. But his role is not really impressive and has no super power. The same movie had the famous character Silver Samurai but portrayed him in a manner which I felt disappointed. So I'm OK if Sanada gets to play a MCU version of Silver Samurai in future. It may set both the actor and the character right at the same time.
That' my thought. How about yours?
