Can you create your own Star Wars species

you could make one up but you would have to make a book with it to make it a real part of star wars



if i made one it would live in hives have 4 legs with a pincer mouth
it would be the size of a bug to a size of a dog with a cube shaped center the legs would come from the side
it would have an eye that is a varying color
it would be like a dragoon from starcraft but smaller and a different color top(its eye)
