Cargo Pods as Commodities

Probably in the wrong section, but I needed to put it somewhere. Plus I can’t seem to find any information pertaining to this subject anywhere…

What I’m trying to do is make the external player equip-able cargo pods act both as commodities (the pod itself as a bulk form of the good; doesn’t add to cargo space) and as a form of destructible object that upon being destroyed drops the commodity in question (the smaller form). The closest approximation would be the storage depots just outside Manhattan, a cargo container when equipped, but a commodity upon death.

I’m having some trouble on the implementation of this little idea, could somebody please possibly point me in the right direction.
