I've been thinking about making a Kitbash of Cliffjumper based on the movie figures. I know that most people would think of using one of the two Bumblebee figures, but I think that Swindle would make a better base for Cliffjumper, rather than a basic repaint of BB. My major concerns, are what to use as a head and whether or not to replace the belly-cannon. As I have not found Swindle in stores, can anyone tell me whether or not there is enough room for an alternate head without compromising the transformation?
