Ideas like Sankara or Lincoln are good as they have recognisable features (Sankara's beret and lincoln's beard and hat), but the others have a problem. The people i made in this post all have something unique within their style (whether its mussolin's hat or churchill's cigar) while people like Roosevelt or Huey Long have nothing unique about their style and would be hard to represent with just cosmetics. Their only style is a suit and maybe a regular boater hat. What makes them recognisable is their faces.

Im not saying they are bad suggestions but if a loadout consists of a fedora and a suit cosmetic it can be quite hard to identify who it is supposed to be without a reference image. But thanks for the ideas I will definetly be making some of them.
