The IDW comics Revolution event melds together the Transformers, GI Joe and MASK sagas into one universe. I think it’s fair to say that if a Hasbro Cinematic Universe (HCU) is put into effect, of which the Transformers Cinematic Universe (TFCU) would be a part of, that event could be a likely template/influence for building it up. AOE has already featured elements of the IDW TF comics, with heads in labs, Transformers being hunted, humans working with Decepticons, and the appearance of Drift and the Dinobots. So it's fair to say that future films may draw a lot from the IDW comics. As far as crossovers and comic adaptations go, I’d like to see an adaptation of Tom Scioli‘s “Transformers vs GI Joe” comic. It’d be a standalone story and perhaps near-impossible, but it would be awesomely insane if they could pull it off.
