Can I 提交 my OC to the My Little 小马 Friendship is Magic 显示 on Hub?

Hi, I made an OC a while back, and I have already thought of a story for him. His name is Prince Darklight, he is an adopted cousin of Celestia and Luna, and he was originally the son of Sombra. Celestia and Luna gave him the responsibilities of the eclipses, hence the name Darklight. A solar eclipse is his cutiemark. One day, his birth father returned, and in order to save Canterlot, Darklight fought Sombra, and as a result, Sombra broke his sons horn, reducing his magic powers significantly. I would really like for my OC to be on the show, but I have no idea how to get it to Hasbro 或者 Hub. I even wouldn't mind if it was a background pony, but still wouldn't fit, cause hes an alicorn. Could 你 guys help me out?
