satoh, good luck. some one i know has offered to do them

that is a little demo of what they would look like and size.
please say if they need to be bigger. compared to the series there look the right size but it depends on what you say.
edit
i asked if we could have one that size (for a baby one) and the rest alot bigger. i showed him the image on here to give him an idea.
edit
he has finished the baby grunty sprite, what do you think

the person who made it called him/her self Sakura Martinez so credit it by that name.
