So I was scrolling through that costumebin.doc when something caught my eye. After much scanning, eye melting, and guessing I managed to put these together.
There were a lot of options for chest/shoulders/gloves/boots which most likely added spikes and had left/right only options for shoulders but there seems to be an FX part in the coding that isn't working. Or I just don't know how to put it in. I found the same problems with Cosmic Corsair and Apocalypse pieces. It is also likely that there are some head detail options that I missed.
Here is the demo info for each of the body types.
