Complete DxD = Complete Ophis...

CxC = satan-class ? he beat barakiel with it.

Here my speculation :

AxA is Great red's power who is sleeping in is body. (that include a giant dragon form)

ExE is a new armour above DxD.... with a fusion of both Ophis and Great Red power that give something else..... Something much more powerfull
