Expand weight carry buy option-TALOS Exoskeleton

It would be cool if you could add the option to buy a very expensive exoskeleton which would allow you to carry more inventory(US army Talos style?). It could boost speed, or retard it depending on how the balance worked out w/the rest of the game-you could even make it so you have to buy extra batteries to keep running it(ammo boxes could replenish battery supply). Combine this with the ability to carry extra ammo-you could have support be a mobile ammo carrier for the rest of the team.
