Actually there are multiple different suggestions like this (duplicate) not only limited to that one. The one you pointed to however was just a derivation for only elements.

Anyhow on topic, I don't think this a good idea, besides you probably won't be able to carry it with the extra weight.

this feature is literally on just about every other server in terms of having a grenade + meds.
