Naw, you see one you seen them all.
My army will be fairly clone like. 
"you never know"
I'll always say
I started like you...my ACW northerners had to have even same hair...after a while, I decided to make sure no two faces look alike(combination of different hair & face) but until today, they all still stand in the same pose, have exactly the same pouches on the same side...not life like but then thats how we like them...I remembered you said yours had different hair/face too right? 
Yeah, a few of my people
(at least the next Samurai I will buy)
will have different hair styles.
(There will be 6 of them, one will have the "Samurai hair",
2 will have Regular Black Hair, and 3 will have Long Black Hair.)
And I have 4 or 5 different faces.

But like you they will have all the same armor, And the same weapons.
(When I start buying them in bulk they will have different weapons,
But these first few will all have spears.)

I will also have a second and third and fourth style of armor
when I start buying them with the new Specials.

(CANT WAIT!!!)
