Natsu's Dragon Force + Lightning Flame Dragon mode

I like the idea but the question is since Dragon Force is related to the whole becoming a dragon thing without the anti-bodies, would that even work? I mean maybe he could use the lightning but since his actual dragon element is fire I'm not sure.

The same rulings apply with Gajeel's Iron Shadow Dragon mode if he used the Dragon Force. We'll have to wait and see.
