I chose "Ach" (in spite the fact that the options were a bit manipulative

)
Although most changes would result in disadvantages mainly on your side there are some problems I would see in game play.
1) When attacking the rulebook tells you to bring all stands (with enough movement) in contact with the attacked unit. A normal unit would have 3 stands - yours would'nt.
2) When your unit would be attacked in the flank it would be unhandy to tell which stand touches which.
3) You would easily give away flexibility for looks. There's not only the column when placing units - many infantry units are placed in line. Your line would be at least a bit shorter.
In some cases it would be harder for you to react to and move around terrain.
I am very sorry - but I would not even like to play against those units - because the smaller frontage would in fact falsify the attributes and the qualities a unit has (even if most negative effects were on your side).
The smallest defined "unit-cluster" there is is the 2x4 stand - and there's a reason for that.

P.S.: I guess you are in fact aware that the attributes "attacks" and "wounds" defines the attacks and wounds of every single stand, are you?
