Definitly push the gun mode cause and point out how rediculous it's size is and that all we really do need are bright end caps/barrels on them.

As for lines, I'd go with prime and bumblebee from g1-classics-movie-animated.

But me personally, I'd take g1 jetfire and classics jetfire.

Oh yea, take some same universe/henkeis and show people the superior difference between the two in henkeis favor.
