I imagine this to go with a storyline where Anakin takes over Tatooine from the ground, rather than giving it the quick end of Alderaan.

Maybe it started as a one-man vendetta against the slavers, but is spiraled into a scorched earth campaign to decimate the entire planet.

I picture him emerging out of a sandstorm, his tattered cape billowing in shreds, his helmet scratched and dinged from scouring sands and blaster fire.

He boards his shuttle and takes the pilot seat. A hologram of the Emperor appears "What do you have to report, my dark pupil?"

He replies with the eerily flat confirmation "Mission complete, my master."

"Very well. Return to me. There are more worlds that need your attention."

As the shuttle flies away you get a view of the carnage on the ground. Whole patches of desert sand have been melted into charred, cracked glass. Jabba's palace teeters and burns on a crumbling cliffside.

Tatooine is a dead world forevermore.
