I've just discovered this mod and i thought you might be interested in a lot of uniform resources from this period. This is an OSP we have released on the Taleworlds forum, for mount and blade.
All these models would work quite well and look good in the Total War engine.
You should download it, and download Openbrf too so you can check them out, and then put them into your mod.
We have, from the Victorian period, French, British, Prussian/German, American, and Japanese, covering a large amount of different regiments.
