Was thinking. I know! I know! That's a bad thing! Anyhow, we have been told that we would see the Dinobots back in this film and was said Grimlock would have more of a role and first seen in the beginning of the movie. So that got me to thinking. At the end of AOE, the Dinobots and Galvatron are the only ones left that would stay behind in China right? The Dinobots more than likely ran back to the crashed section of the Knightship and would have claimed that as their base of operations. Most of us think Galvatron will somehow be changed into Knight Megatron and do so the same way OP did on the Knightship. But the Knightship took off back to the Creators, so we assume. But what if Galvatron goes to that crashed section knowing that there might be a way to trigger something in that ship to call the Knightship back? At this point Galvatron would end up fighting the Dinobots who would be there early in the movie. Maybe even killing a few! Leaving Grimlock and maybe one other left. The Knightship shows back up, the Dinobots dead and badly damaged are out of commission and Galvatron takes his Prize, the Knightship. And gets his knight upgrade?
