Leader graphics mod?

[Liebchen]

I find it odd that the leaders all have three stars. It would make more sense to me if the brigade commanders had one star, the division commanders had two stars, and the corps commanders had three stars. Army commanders could have one large star.

Does anyone know if there are any mods out there that are sort of along these lines?

Alternatively, does anyone have any ideas about how hard it might be to make such a mod? I'd be wiling to try it, but can't find the graphic for leader icons.
