It’s certainly a very ambitious plan and works very well as story. The battle will be getting it to work on screen well enough for it not to be a distraction. It’ll also be a challenge to keep the small story beats from season 3 such as Din’s moments teaching Grogu.
I don’t have any experience with special effects so I couldn’t even contemplate this level of change. I’m intrigued to see how well you can pull it off. Good luck!
