A nice little project on the Lead Adventure Forum http://www.lead-adventure.de/index.php?topic=23141.0 really got my juices going. These beastmen are incredible. All done by Funky Brush. I made a quick wallpaper for my pc at work so I would remind myself to think about how I would do them. I have named them 'The Braying 29th'.
I have also been digging for bits on ebay and the internets to see what it would cost to play with this idea. I have tons of unpainted 28mm napoleonics, just not plastics. So maybe a little harder to pull off as Funky Brush's work was done with plastics, but still doable I think.
Right now I'm thinking:
French - Elves - Maybe Dark Elves
British - Beastmen
Spanish - Skaven/Ratmen or Goblins
Austrians - Undead(white uniforms, eastern european, etc.)
Russians - Orcs and Goblins?
Prussians - Dwarves - well this is the Baron's request so we'll go with it.
I have found a bunch of suitable heads and legs and arms in plastics. It will be fun to try to marry them.
I also found that the 40k Kroot heads are incredibly easy to use as well, so maybe I have to find a spot for them.
This leaves out the lizardmen, which would be fun. Maybe they can be the Portugese or Italians.
