Just because some of the characters have similar personalities, doesn't mean they would be a good addition to the crossover. The whole point of the big four crossover is that they are all 3D animated characters, the crossover wouldn't exist if they were all different styles. That's why you don't see other 2D Disney or Dreamworks characters on here.
