The more I think about it, the more I think Bagel’s idea is great but is going to likely require a lot of AI/custom work.

Here are my thoughts on how it can go:

Boba and Din have a conversation, maybe over radio early on about the Hutts with Boba giving him a warning to not trust them.
In the 3rd act, Din and Grogu escape the castle the dragon and into the woods. Din does not get sick. They do their preparation and ride back in to kill the hutts.
It is Boba doing the run as I described above. He warns Din and Din tells him to do it anyway. Uh AI moment, seismic charge???
Din and Grogu escape as before. Din runs into the woods. NOW we get those shots of him starting to stumble and get sick, being chased by the robots. Those are great “dying hero” shots.
We go through that whole sequence, Din dies. The shots of Grogu with him already present in the movie are actually super emotional in the context that it is him dead, not just sick. Grogu gets his goodbye.
AI of Boba arriving on the planet, looking for Din and Grogu. While Grogu is on his mini adventure, Boba finds Din’s body.
Eventually, it is Boba who finds Grogu. Boba watched his father die.
Boba takes Grogu back to Luke which is how the movie ends. You get a hand off of Boba to Luke, which will show great development seeing how Luke put him in the pit. THis whole sequence will likely be completely AI so this is a challenge for sure.
Nice cause Luke ALSO saw his father die.

It 100% feels like Favreau filmed this movie and left Din dying as a possibility that would have gone something like the above. But they decided not to go there, probably in the hopes of non fans watching it. Which to be fair, I heard of a lot of first timers watching this and enjoying it. I think Mando and Grogu is actually a great intro to Star Wars.
