That last image would imply that Optimus didn't get any bigger when he upgraded.

I think we'll get something similar to Brave Dagwon where the combiner parts are just built up underneath (but removable)
Superion combines in the cartoon the same way as Menasor with big blocks for lower legs and jets strapped to the back. I can't imagine the jet itself will be permanently compromised by the combiner parts just like Motormaster's truck cab formed a robot without requiring any of his combiner parts.
