So instead of going on with the Brony idea.. we need a fresh angle to call our own.
We could do SuperDeformed Runners, so big eyes/big headed short versions of runners on the cover

(wait, doesn't CanRay look like that normally?)
Or replace the various races with quasi-animal humanoid forms like in
Apocalypse MeowSo you could use something like :
Human = Monkeys
Orc = Bears
Elf=Cats
Dwarf = Badgers
Troll=Elephant/Rhino/Turtles?
