Having the Sharingan is the only requirement for Izanagi and Izanami yet, we don't consider those techniques for every Sharingan-wielder. Simply having the requirement is not enough, it would have to be shown that he can use it in the manga for it to be considered. Otherwise, we would have to take in account of all the techniques every character can use or have shown to use in non-canon material despite not being shown in canon material.
