Nope, and here is why. The results of the GMG didn't actually CAUSE the dragons to show up in the first place. So in other words, if rogue made gajeel lose, then Hisui would not go through with using eclipse as a cannon.

How do I know the GMG results doesn't cause the dragons? Because in an earlier chapter Igneel says something a long the lines of "Our time to take action is approaching" because of the dragon king festival. So who wins and loses doesn't matter to the dragons, they're showing up regardless.

The only part that confused me the first time and still does is what you mentioned before, the shadow saying "i don't know this gajeel."

Which could mean that, he did not exist in the original time line so could be rogue... So now it brings us to a stalemate and none of this makes sense.
