Well I wouldn't have minded the odd shako showing up. Speaking of which, could the green Landwehr have a random chance of one? or is it too late?
Also, don't forget bicorns for the heavy cav officers.
Don't worry I haven't forgotten about the cav shakos, I started looking at the Austrian ones eariler today (two blob birds with one stone)
I'm afraid that changing the model paths for NW is impossible at the moment, we can only work with what we have :S
One thing I would like to see is the ability for multiple skins to be assigned to the same unit for extra variety. I know Hinkel did it for North and South.
To do that, the mod (which is currently just retexture/reskins/remodels) would need it's own modification files. This means you will be unable to play with other people, unless they have the mod.
^This applies to hats as, even more so, at least we can tie pants to tunics with the uniforms easily
