Now thinking more about it, I do say completely ax out boba fett from the movie.
Instead, there could be an extra character added that could be an imperial spy. Kind of like in The Force Awakens you had a resistance spy and an imperial spy …
Anyway, it shows a guy sneaking off the hallway, maybe after Luke kills the rancor. He could be in a cloak, or looks like some kind of bounty hunter or something. He Takes out a communicator and says “Inform Lord Vader Skywalker is here.”
If there needs to be more added about this concept: After holo escapes, the video screen can be used with an officer reporting to Vader that explains that troops found the Palace empty and rumors/reports that Jabba was killed and Skywalker escaped. Vader can be silent … or just choke the guy … whatever is needed.
It adds a good connection for the first part of the movie with the rest. It also goes with the scene with the emperor commenting about Vader’s search for Luke and telling him to just wait for Luke to come to him.
