Using HMW rules for an RPG Concept

I've been playing this game for some time now and for some crazy reason it occurred to me. What if HMW rules were used in creating a roleplaying system? But I had some questions to translate this into rpg terms, and some thoughts for adding to the HMW.
First the thought for HMW. Is there a way to add on to the armors available for installing, or perhaps changing the list to reflect actual armors used in the transformers genre? What I mean is this. I've never seen Iron, Aluminum, or U238 actually being used in any of the series (as examples) or mentioned in any tech specs. But I have seen or read of Durabyllium, Malibdium, Polymer-Steel, Sillenium Steel, Stainless Steel, Titanium, and Trythillium Steel. What I want to know is if they can be added with their own stats and such.
Second, regarding actual number crunching for roleplaying I have 2 questions now that I remember them. 1)Weapons are rated as dealing damamge from 'Light' to 'Incredible'. Are there assigned percentages of damage dealt to these ratings? If so, what are they? 2)I understand damage that is dealt to a transformer is absorbed first through Armor then Endurance. Are there specific amounts of absorbed damage assigned to each armor type and to each rank of Endurance? What would they be?
