Stalker Secondary : Body Modification

I have had this idea pinging in my head for a little while now, since hooking up with the MMO Shadowrun, the idea of body modification.

Now I do not mean extra arms and legs, but the "internal" and skin mods that happen. This is what I have scribed up. I probably still need tweaks on, but here it is:
1. Hide lvl 1 (1.875% def)

2. Underarmour lvl 2 Auto Res(All but Psi) Res 7.5

3. Metal Weave lvl 4 - Toggle Def: Melee(14%); Res(defdebuff)(15%)

4. Mental stabilizer: lvl 10 - Toggle (Res Psi 20%); Res Status(10)

5. Sharpened Eyes lvl 16 - Toggle Def Range/AOE(14%); Res(defdebuff)(15%)

6. Antibodies: lvl 20 - Click: +Maxhealth; Self Heal (40% both)

7: Titanium overlay: lvl 28 - auto Res(smash/lethal) 10%

8: Flash Bang: lvl 35 - Click -to hit; -percep; chance for hold (50% chance)

9. Synaptic Overload: lvl 38 - Def(M/R/A 22.5%); +res(status); +speed; +recov

I am open to all opinions on this incarnation of this idea.

Not hating on your or anything but:

1. How does Flash Bang fit conceptually in a set about modifying yourself?

2. How is body mod not covered by any of the other sets?
--SR = modified synapses and reflexes
--WP = modified body and mental foundations
--Regen = modified metabolism

Now if it was giving yourself extra legs or increasing your size or something, that's at least something different from the other sets (if not impossible with the current game engine).

It's interesting that, I can't really think of Any Defensive Powers that aren't covered in some way by the current allocation of Defense Sets except for maybe Intangibility, Which is just so much more than the defense powers in this game can handle, and is kind of a one-trick pony type of power, or some Kind of Morphing, which again, this game can't really do.

Energy: Forcefeilds of any kind
Invulnerability: ANYTHING you want
Regen: ANY type of healing you want
Super Reflexes; ANY type of Spidey-sense or agility you want
Willpower: Any kind of Training or crazyness orabnormalities or internal strenght you want
Sheild Defense: It's a farking SHEILD!
Dark Armor: I guess if you need that kind of thing
Firey Aura: It's FI-RE!
Ice Armor: What else do you want?
Electric Armor: Bzzzzz, what do you want?
Stone Armor: Seriously, It's rock armor

Perhaps Air/Storm defense? You can either deflect incoming attacks or just move yourself out of the way using air currents?

I'd say Telekinesis because WP really has nothing to do with affecting other things with your mind. Literally bouncing swords and bullets back with pulses of psionic power sounds different...and Energy Aura *could* fit that bill...but it has *no* psionic protection >_>

I still think Goo Armor would be entirely unique. Who hasn't thought of at least 1 character who can be splattered into a puddle and reform back into normal in a matter of seconds? Someone throws a punch at you? Their hand gets stuck ^_^

A suitable techy defense set with techy implants and game mechanics could be something but is more origin specific...

Kinetic Aura? Because Energy Aura, again, doesn't fit that bill. I already have a concept for a guy who can absorb an enemy's attack and fling it right back at them.

Can't think of anything else
