I just realized today that, yes the dragon slayers consumed another element to gain their dual elemental state. But they only gained their dual state only by consuming not from just any element, but from the same element of another slayer (Ex: Natsu consumed Laxus's lighting and Gajeel consumed Rouge's shadow) all who were dragon slayers. So again, it does seem possible for a god slayer to gain a dual state, but it would have to come from another god slayer's element. The only other god slayers that I'm aware of so far in the RP are Janice who has lightning and Lazarus who has light (I think).

My knowledge usually comes from just the anime and not manga, so I don't know if the manga discussed about the possibility of it.

What about when Natsu ate the blue stuff to beat Jellal?
