Ymir's titan propably wasn't even designed as Jaw Titan back then so she looked like normal titan, Pieck was supposed to be male and it was propably changed after return to shinganshina arc so changing her titan form would be weird, same with Female Titan, i guess we won't see this titan in male hands.
