Just as we can build a spacecraft from the ground up, it would be neat if we could customize the Kerbals' spacesuits. The way I envision this is a separate tab for spacesuit customization. Different suits/components would have different benefits- Onboard power would be limited. Your Kerbal could have gizmos, but you'd have to manage their use in EVA. Your [future career mode] budget would also be limited, so you wouldn't be able to kit all your crew out with everything- you'd need to specialize. At the bottom tier you would have the most bare-bones suit, basically just a bunch of garbage bags duct taped together with a fishbowl for a helmet. Some suits would be hardened against [to be implemented] radiation, or more resistant to impacts. Some might allow for better dexterity if you had to perform science or repairs in space. You could equip your Kerbal with a parachute allowing him to land on an atmosphered planet from space . You could give him varying amounts of RCS pack fuel depending on how much space/weight you need for other things like toolkits, batteries, lights, and sensors for performing science.
