I think I would completely base it in the dark purple (maybe mix it 3:1 with their dark blue) and then zenithal dark blue with the airbrush. From what I've seen the key to making the indigo scheme look good is a ton of green geometric designs, so freehanding will be your friend.

I do miss how versatile it was, but I think a change was need because of how stupid things could get (like in FotA, where you could give your warlord contemptor dread a tiny powerdagger to still get an extra fist attack on top of whatever ranged gun you wanted). I definitely think they overcorrected in 3.0 when they removed all attack bonuses outside of lightning claws
