the only problem i have about all this boba fett surviving, or basically doing anything else except for dying or being completely absent is that it would just be really distracting to the plot, and wouldnt add anything to the film. if boba had a bigger role in ANH and ESB then it would be different, but in the context of the movies, he is just a cool looking plot item.
id just have him decapitated, or at the very most, replace the burping muppets frog from outside the palace with his ship taking off.
