How? (And I really am asking. I'm not trying to be... whatever the word would be.)
The way I'm picturing it, the explosion would be much more satisfying than the way it just goes 'pop!' and disappears.
Besides, everyone on the thing would still be dead and the Rebels are saved. The victory is just as before, except there's a chunk of charred Death Star left floating in space. That doesn't take away from Luke any more than building a brand new DS does.

I love your ideas for Jedi! Has anyone ever edited the Luke in the cave scene to make it look like Dagobah?

Thanks! I haven't seen that scene done that way, but I've seen the same effect (background replacement) done by others on other projects enough to know that it's doable.
