First, Grim Reapers are God, that why Bennia is a Demigoddess.

"“Yes, Bennia is a Grim Reaper. Even though I said that, she is a Demigod. Half Grim Reaper and half human.”"

- Volume 14

Second, Balor already lost his divinity.

"《That’s why I’m telling you that I’m a fraction of Balor’s consciousness. I already lost my divinity and only my power of evil remained. The actual Balor was killed by the God Lugh after all. I am Balor but not Balor. I am “Gasper Vladi”. Sacred Gears sure are interesting things. They can possess anything from legendary Dragons and monsters to even the power of an Evil God. The God from the Bible who created the Sacred Gears truly must be a terrifying being.》"

- Volume 16

Third, so just because Ise has Ophis' power doesn't automatically means he will or can become a God, as Balor showed "Power" and "Divinity" are separate things. Ise may have Ophis' power but there's no guarantee that he will become a God. Ophis may not have passed down her divinity to Ise. We can argue about the Dragon Deitification thing, but at the moment we still don't know how Ishibumi plans to go with this yet.
