YES! I was just thinking of that myself. I think it would be perfect as a D&D setting! Heck, we already have rules for vehicles in Avernus!
They got a third party (I want to say Renegade Studios is the name?) working on a Transformers RPG (they also got a Deck Building game on the way). I think they're supposed to do other Hasbroverse properties.I could imagine them making RPGs using the D&D 5e engine for other product lines owned by Hasbro, like G.I. Joe, Transformers, and Power Rangers.
It's not what I would want, but I could see them doing it.
As far as fantasy settings are concerned, I also agree with the OP that something alone the lines of Council of Wyrms is not only possible, but likely. Could tap into the current popularity of both Kaiju and superhero movies.
