Here is my prediction for the subsets if a 12th. All New Series of Wacky Packages is green lighted for early 2014 release (Around the time of the 10th. anniversary of the relaunch of Wacky Packages in All New Series):
a) Another Rude Food menu subset (This time could include Wacky Packages style menus of these restaurant chains spoofed: IHOP, Cracker Barrel, Hooters, Tilted Kilt, Perkins, Denny's, Famous Dave's, Longhorn Steakhouse, and Bahama Breeze - Those would be my guesses)
b) A subset spoofing comic book covers - My guesses would be: Batman, Wonder Woman, Justice League of America, The Incredible Hulk, Fantastic Four, Archie, Sonic the Hedgehog, Star Wars, Peanuts, and Adventure Time. (Sorry, Spider-Man and Superman, you had your own Wacky Packages ANS comic spoofs in the past - Spitter-Man and Superham, respectively!)
