It's come across my mind several times and I need some ideas on how to progress on this project. What I certainly want to do is possibly making two transformable guns for ROTF LC Optimus Prime using, of course, his two gas tanks and the Buster Prime gun as a reference. To put my idea simply, I would like to somehow replicate only the tank/barrel part/attachment of the buster gun, reverse the structure to fit the opposite end accordingly, and finally add a few parts that extend from the gas tank itself, such as a handle or other accessories for better accuracy, therefore giving the figure two guns. The guns them selves will not be completely accurate for obvious reasons but will give the satisfaction of transforming parts. Any sort of feedback is greatly appreciated!
