People That Should Be Custom Characters, but arent...

first of all let me start with sticks the badger, the rest of team sonic
sonic, tails, knuckles and amy ALL have sprites, but sticks doesnt
all of the MK8DX dlc characters should also be added, i find it silly no one has done that yet
others
baby peach
baby daisy
baby rosalina
cranky kong
tiny kong
dixie kong
and finally, actually good sprites for the koopalings
can you give me a reason why the others dont have any sprites even know they are noticable characters???
