I have zero problem with them being voyager if it turns out to be true - all those construction vehicles are bigger than those that make up the Stunticons for example (since Motormaster doesn't have a trailer and all). Predaking was always accepted as bigger than the other Gestalts in fiction, even if it was only by a head. I reckon the Gestalts should be different sizes based on the alt-modes/bots that comprise them and how many different bots they comprise. Though I suppose by that reckoning Superion should be huge!
Even if we look at IDW, Menasor was only about 3 times the size of Ultra Magnus, yet Devastator was smashing gigantic bridges with one punch and crushing jet fighters in his hand
