This is freaking awesome. If we decide to keep the Sun, I vote for putting dust-rings on it, sort of like Jupiter or this.
Why stop with the Sun? Why not customize the whole universe generally look awesome? If you can re-arrange star positions, we could get some seriously awesome constellations out of that... and screw with stargazers at the same time. Granted, it would take millions of years for the light to get to Earth, but it'd be totally worth it.
