Fluff Check for Southlands Warband

I had an idea to do a warband of rich human nobles leading hunts into the jungles and plains of the southlands to find and take trophies. I currently intend for the timeline of the Southlands to be around the time of Mordheim.

My thoughts for the warband was to have several noblemen hunters/explorers for the heroes with a local guide and the hired help (porters, bodyguard, dogs).

Heroes would have significant access to blackpowder gear and the feel i want is heavily geared heroes with guns and then rather poorly geared henchmen.

The Southlands guide could be from Araby, Ubuntu or Zamula and would grant various bonuses depending. Thinking Araby would have better trade contacts, Ubuntu would be anti-animal stuff, and Zamula would be protection from environmental hazards.

Would this even make sense for the time period and setting of Warhammer? Or is it too anachronistic to work?

Darkest Africa meets Warhammer? ! love it, anachronistic or not, I'd still love to see Empire Heroes in pith hats. I think it could be all kinds of awesome!

I hope then to make it a reality! Shoudl the Pith hats be a special helmet? Or just a helmet?

I think a pith hat wouldn't even be a helmet as its to protect your head from the sun, not from blows. But there are some Empire models with very pith-hat-like helmets (pistoleers I think?) so just normal helmet rules would be fine.
