In a large bowl, stir together the yogurt with the chives, garlic powder, onion powder, chili powder, Worsecestershire sauce and 8 oz cream cheese along with 4 cups of shredded cheese.
Use two 6" round ball tins. Line the tins with plastic wrap and then fill each half until full. Cover with plastic wrap and freeze solid. The freezing is the most important step!
Cut the salami and pepperoni into squares and rectangles. Cut a slices of mozzarella about 2" wide and 1/4" thick and cut out a hole in the center (OPTIONAL: Use an olive to keep the center from shrinking). Cut the proscicutto into ribbons. Chill until the cheese has frozen.
Remove one half of the frozen cheese ball and spread a thin layer of cream cheese on the top. Flip the other half of the cheese ball on top. Use a spoon to make a divot in the side of the cheese ball - about where the Death Star's laser beam would be. Cover tighly and smooth the ball with your hands, pressing in the divot. Place on the serving dish. Chill for at least an hour.
Uncover the cheese ball about an hour prior to serving to hasten the thawing. Generously spread the remaining cream cheese on the outside of the cheeseball and then use the proscicutto riboons around the center of the cheese ball.
Press the mozzarella into the divot. Then use the squares of pepperoni and salami to make the 'paneling' on the Death Star. Wrap with plastic wrap until ready to serve. Enjoy with chips, crackers or TIE fighter chips! May the Force be with you.
