Or, instead of having this complicated system, why not just add a group of microblocks and a system by which you design your own equipment? A factory GUI that lets you place blocks in a mini-environment, perhaps?
Different power cores and explosive types, of course, would have to be manufactured and possibly bought - but it\'d be nice and in-line with the gameplay style. To add to it, these microblocks are to be given block destruction possibilities so that killing a person depends on punching through their armor and/or destroying their gun. Follow up by looting their gear if you\'re good enough to knock their head off without breaking anything.
It\'d be awesome to prove people that spikey and badly crafted gear is stupid.
