I think one way round it will be to find my starting warband list and define the different groups a bit more.
Alternatively I'll experiment with skin tone and detail on the cloth to break up the similarities. I am going to be using some white on the Greatswords' clothing in order to deal with all the frills without painting a wall of green.
On the other hand I want to get everything painted quickly and uniformly so I have a nice looking warband that I don't mind gaming with since it hasn't taken years to paint (physically, it's been years in the making).

@static grass- thanks! I don't remember the last time I assembled a stock GW miniature. It could be ten years ago now
