No pics (as most of mine are now in a steel container at a mystery location in the deepest recesses of the South West of England) but, as mentioned above, many of the heads can easily be used for survivors.
I may even try this with mixed US GI's and WWII Germans (as same scale as Z Vixens) when we're ready to move in to the new house.
I wanted to try it with Shock troops, but the Shock troop bodies are Heroic 28's so the heads look a little small when placed on the torsos' of the Shock troops.
The arms however from the GI's or Germans added to some of the torso's of the Z Vixens are as close as 'darn it' to making the female bodies looking like armed survivors.
The female torso wearing the trousers (one of my fave sculpts I've painted as a Z so far) would easily pass for a survivor as she's far less long gone as some of the others.
That being said, Jim did point out that with some Green Stuff, some of the other torso's could easily pass for the living. It's also a nice way of having 'Before bitten' and 'After bitten' figures to represent characters.
