Mm, I did consider having a general "Husk" version where I'd denote what was standardized before moving on. Such as the fact that all armors are between size -1 and size 1 with size 0 being the standard. They need to fit the pieces inside yeah? Also, I'd rather avoid the situation where a player decides to make his mech some sort of combined mech/life support system and have it as powered armor. I've had people tr that crap before out of worry that I'd have them jumped in the night.
