Regardless, I know Octorox has already completed an alternative audio track for ESB Revisited in the past for prequel continuity (Boba voice and Yoda being only “a” master that trained Obi-Wan). This is something we can also pursue for this project.
Ady’s test here for ROTJ is awesome visually, and will only be more awesome once Boba actually sounds like Tem. Whether we have to make a fan-made alternative audio track or not, we’ll still get there, eventually.
