I know that some of the weapons are stored in the r4items.bundle. I think that models usually have the .w2mesh extension - so try searching with that as a keyword. EDIT:: I've tried replacing one of the inventory icons by placing an edited file in what I assume is its proper folder structure (in this case, it's the Enhanced Hanged Man's Venom, at gameplay/gui_new/icons/inventory/oils), in the following folders: content0, content0/bundles, patch0, patch0/bundles. No luck. Perhaps there is no override structure and any content has to be bundled/cached. Should we post a thread on the official forums about this? I never dabbled with W2 modding - could someone enlighten me as to how its override was set up?
