^ This would be pretty neat.

Also perhaps adding interchangeable armour pieces, like engraved/enameled/studded plate for pauldrons etc on the knight, scale/leather/chainmail for the armour under the vanguards surcoat etc. Also even bring across some of the small detail items they have in the customisation options for DW (Horns etc).

Sure it might add to the whining we got when they introduced customisation of colours, but people get used to it.
