last week i heard about the game "Histwar les Grognards", its a game like SOW but not that good

however, they are developing a 1:1 scale of the soldiers (in 3D), and it would be possible to get 500.000 Soldiers on the Battlefield...

so my question is, is it possible to to this with gettysburg? SOW has only polygons...and Histwar 3D.
I want to see the Ironbrigade in 1:1
