True. But Omni-Creator also suggests that all the all powerful deities of all fictional verse are one singular entity, just in different forms. And if this entity truly exists outside of the Totality then it has the most powerful power, Omni-Creator, ever. If it exists within the Totality however, then Omni-Embodiment is the most powerful.

Even over AC. Because it IS that as well.

As for Eru, from an in universe perspective, he is not subject to change. Tolkien never said he was. Granted, he never said that Eru WASN'T immune to change, but the way Eru is described it's a safe bet to say he is. That and Tolkien probably would have, if he was still here, called us all idiots and chewed us out for even thinking about changing his work.
