Hell yeah. Grimlock the middle. Strafe the Backpack and Weapons. Slug the Right arm, Scorn Left arm, slash Right leg and Slog the Left leg
Anything except EXTINCTION! I hated that Version of the combiner. If it's like Volcanicus...I won't mind

No. The dinobots have received absolutely no characterization, quite the opposite, they've been reduced to comic appearances. If you can't even give a single dinobot a good role, why on earth would I want all of them together. We'd just wind up with another testicle joke, further reducing the impact of characters who should have been bad-ass shock-troopers. Reboot.
Yes. He would cause too much collateral damage, which is not good for Autobot, and such size is rather a flaw.
