It's been discussed a few times. I wouldn't mind seeing 1:1 myself. The problem with having more figures per man is that the sprites would have to be smaller in order to fit in the same area of ground. The "footprint" that a unit occupies is properly to scale historically.
There is also a problem with how many figures can be displayed and animated. Even just doubling the number of figures would affect frame rates, and some computers wouldn't be able to handle it. The game was designed to run on the lower end computers that wargamers have typically owned.
