Smoker Swep Request

Okay, so I was wondering can someone create a Smoker swep similiar to the one in Left 4 Dead? I was thinking it can be like the barnacle and turn NPC’s and Players into ragdolls before it does damage. I would do it myself but I am absolutley rubbish at LUA and scripting. Also can you include the claws as a melee weapon?

Silverlan’s new Half Life Reniassance (I can never spell that, and the steam browser has no spell check :/) has a barnacle gun. When that comes out, you can change the model to something from Zombie Panic: Source.
