The Energon Pub

In 1987, the G1 line proposed the two autobot clones, Cloudraker and Fastlane, identical robots (with little differences on the back) with completely different alternative modes (car and jet).
In 2008, the Animated line proposed another twins pair, Jetfire and Jetstorm, two identical molds with different paint and head (same alt mode, jet; they combine to form Safeguard).




I would to point out an analogy: the Jetfire and Jetstorm alt mode is the same of Cloudraker, a jet.





Maybe a G1 tribute, mostly in the back: both with this part formed by the robot legs, with the wings on the same legs and the feet in the same position.
