The list of available cyber (or g-mod) implants is rather short. Has anyone thought of adding Hardpoints or something similar to allow for additional cybernetics in arms, legs, cyber-eyes, etc. perhaps borrowing from Shadowrun or Cyberpunk. This would be similar to Essence in Shadowrun. I am not suggesting spending 0.1 strain or having dozens of hard points in arms or legs allowing for installation of a plethora of cybernetics. Instead allowing for more cyber-benefits beyond +1 brawn/agility. Perhaps making the stock cyberarm a Type 1 implant with a Type 2 cyberarm having 4 hardpoints and costing 3 times as much. A Type 3 (perhaps the highest model) has 8 hardpoints. Type 2 & Type 3 Cybernetics can blow out on a dispair, when Sundered, a bunch a threat a generated, etc.
The above are just arbitrary values to illustrate the idea.
