Hi, i recently decided to build a custom metroplex out of: Junker metroplex (yellowed) Armada Unicron Cybertron Starscream (large version) My main questions are, how do I get metroplexs thighs to attach to unicrons waiste then hopefully attach it to the torso of metroplex is that possible I have seen it done before. For the arms I want to use cybertron starscream with unicrons hands maybe customize with styrene his arms to make them square and long enough. Also I want to use the LEDs of the Unicron to make Metroplex have light up eyes/weapons? what do you guys think??
