"I think I may have a found a source of Victrix Dacian heads as requested!
However I’m still stuck with the ideas for making Egyptian Marines?"
Newline makes Kappadokians with swords. Easily converted to javelinmen. Not sure about heads swaps.
This problem seems like something that home resin mold and casting would solve, since the Kappadokian hat needs extra bumps. But Dacians sound in theory to be ok except for the bumps and side flaps.
As for Egyptian marines in long skirts I think the only place to go is back to Vendel and Thistle & Rose.
