Remotely possible as in we've seen nothing directly contradicting it, but then by the same argument it's also possible that Acnologia will turn into a pink talking squirrel and try to spread friendship over the planet with rainbow luck-beams from his butt.

So far there wasn't even the slightest and most remote hint at Acnologia being anything other than a bloodthirsty monster.

As for the scene in the manga: It was Acnologia who attacked Igneel, not the other way round. If he wanted to explain anything, he could have done so instead of first attacking without a word and later going on about how he'll wipe out every Dragon and how he's disgusted by the fact that Dragons still exist in this world.

Why are you so desperately trying to turn Acnologia into a hero here anyway?
