I don't think so. As much as I believe that Hamill and Fisher will forever be Luke and Leia, I think they're way past their prime to give voice to younger versions of their characters. Maybe they can use audio from the original movie and blend it with soundalikes recording new lines, like Bob Bergen and Catherine Taber who played the characters in the video games.
