Simple answer you are not allowed to do so ^^
Since valve added Gloves [Arms] it is forbidden to modify it.
So i think thats the reason why nobody is working on a fix.
Update of gloves:

Cause valve thinks, we the server owners are "
creating a confusing experience for players."

*That doesnt mean i dont agree with some stuff.
In my opinion you dont need such stuff like weapons skins to run a good community server but zombie arms were a nice feature for zombie mod and since it was always the most played community modification[I'm talking about modification i know that most people play the casual game ^^] in all counter strike's it is a shame that valve didnt at least released a zombie arm or something like that. Thats not about faking inventory or giving a confusing experience, you play on a god damn zombie server xD. Well at least we can have custom playerskins.
