I was just thinking it would be awesome to have a kiosk that would allow you to create your own pet. Much how you can choose names for your pets, you could have the look, skill set 1, skill set 2, skill set 3, pick if it comes with cards, pick what school, that all could be for crowns. You could also have a randomized one for gold.
I know many people out there, including myself, would be willing to pay big crowns to be able to pick the skills that we want.
