Yorick's ghosts can turn into a variety of different pets (dogs, cats, birds, etc.) His ult can be a pet cage and when the champion dies it sets the champ free. His shovel can be a broom I guess. That's all I got for now. Maybe this'll evolve into something great later with some help.

Needless to say, I support where you're going with this. His shovel would have to be something different though, maybe a broom, lol. But he could have a little bird cage for his lantern.
I have to say a lot of people are using 
now.
