The problem with the Pretender concept is that it can compromise the robot, which is what it did in G1 (contortionists in disguise). Perhaps a better solution is to have the Pretender shells be modular, similar to Siegedom Ultra Magnus' trailer. That way the Pretender shell can be articulated, and the inner robot doesn't have to be as heavily engineered to cram inside a plastic shell.
Or you could have the Pretender "shell" just be a separate action figure that doesn't actually function as a shell.
So for example Hasbro could make a proper CHUG Bludgeon toy that resembles the G1 robot with tank mode etc., and include an action figure resembling the Pretender shell. I don't mind if the figure is smaller, say 9.5cm like a G.I. Joe or whatever (the Pretenders mass-shifted in Japanese canon anyway, while Anglo canon made them go off-world to places populated by giant alien humanoids). Yeah, I know this Bludgeon toy is just a repaint/retool of CW Hot Spot; I just quickly threw this together for a basic visual concept; you get the idea.
