'Meet The Medic' chest-wound Heavy

I was hoping some one could modify a heavy model and make a separate model (so it won’t replace the one I have). The modification would simply be the gaping chest wound used in the ‘Meet The Medic’ video. I have a legit copy of TF2 and it is not in the spawnlist. I think the easiest way to do this would be to modify a copy of the Heavy model.

Unfortunately these is the only reference I could find.
