OK. So, trying to make a min-max Armour Tank. At the moment, I have a Synthetic Morph with the Heavy Combat Armour Robotic Enhancement [16/16]. On top of that I have Body Armour (Heavy), modified with Chameleon Coating, Fireproofing, Offensive Coating and Refractive Coating [22/15]. Under that I have Second Skin [1/3], and Smart Skin [3/2]. And then to top it off, wearing a Full Helmet [3/3].

So all together I will be wearing [16/16] + [22/15] + [1/3] + [3/2] + [3/3] = [45/39]. So basically I should be safe from almost any attack that isn't a Called Shot. I can push it farther with the Ablative Patches and Reactive Coating, but at the moment I don't see that much of a need. But I want to be even more safe, because why be nearly invisible if someone crashing a spaceship into you will still kill you! So here are my questions.

1) Do Armour Modifications stack? Could I modify my Heavy Combat Armour with the mods that are on my Body Armour, and squeeze even more out of it? Could I then modify the Second Skin and Smart Skin with the same modifications? I am thinking the answer is yes, nothing in the rules seems to suggest otherwise. Can anyone find such a suggestion?

2) This one is even more cheesy. Multiple pairs of arms combined with multiple Riot Shields. Riot Shields add their armour rating to your total, +3/+2. Could I buy more sets of arms and equip myself with more shields for even higher gains? Again, nothing in the rules seems to suggest I cannot. Can anyone find such a suggestion?

Now I know that if I actually did this in a game the GM might not be a very happy bunny, but I play an online game with a GM who doesn't like to commit to GM Fiats if there isn't anything in the rules that suggests he should. This would probably pass because I know if I do it, suddenly so will all of the enemies I end up fighting against.
