I think that the Diabolos Dragon God (DxD-G) Mode is also basod off of the  ZGMF-X10A Freedom Gundam.

Because the four cannons that the DxD-G has are almost exactly like the four cannons the Freedom Gundam has, and the wings of the DxD-G are similar to the wings of the Freedom Gundam (when they're spread out).
