So the other day I managed to find an RTS Windcharger at five Below... as well as get a HFTD Hubcap from a Marshalls. Looking at the two figs and transforming them... they have quite a few similarities. The arms fold almost identically. Chest/front hood form the same. Shoulder bits on both shift. Legs are reversed, and are the only major diff. The dimensions are similar... Anyone try swapping their shells? If I can acquire an additional WC my next store hunt... I might try it. With the proportion variation, different bot bits, and reversed legs... maybe a small repaint and you got another set of bots.
