Help needed to create weapon modification system

[HereticSoul]

I'm working on what's basically a WC3 version of the game Crysis, and, as in the Crysis, I'm planning on making an on-the-fly weapon modification system. I'm thinking it would revolve around adding or removing orbs, enchantments, etc.

Right now, I need to find someone who can actually help me implement that system. My biggest problem is finding a way to change weapon models on the go. Any experience with triggering and cameras would be a plus, though not essential.

changing weapon models ? do you mean actual modelling or changing them as attachments ?

Changing them as attachments, mainly. I could use some help with the actual modeling, but that's not my main concern. The models would be pretty standard.
I also need help with changing attack types between different weapons (ranged vs melee etc.)
