Not that it’s a lot of help, but I used an old metal one for my counts-as. He’s the guy with the
JP in this pic. I do a backpack and c-flamer swap to field him as Cassius.
He’s got that nice bionic head going on.
There might be some decent 3rd party bionic heads out there, or check
FW. Not sure if
GW makes any. It might be worth looking at the admech line as well.
