Ultimate skin for Nasus?

How about a Nasus skin that starts out with a smaller dog at the beginning and evolves elemental lux style to where he starts as a wimpier dog (such as a chihuahua?) then evolves into a more medium sized dog (say at 150 stacks?) then finally turns into something like a menacing dog (like a buff pit bull?) at 300 stacks.

If not by stacks then by levels so bad gameplay isn't promoted, through people farming all game to get the necessary stacks

Keep in mind that I am using these dogs for the images that they provide. I know some Chihuahua's could be cerberuses and I know some pit bulls can be great snuggles of love.
