So I painted up the Rogue Trader. I swapped out his chainsword with a slightly more exotic chainsword. I wanted him to look quite exotic, as though he's picked up parts of his uniform piece-meal or tumbled out of a costumer's.
I also put together a Gun Savant from a Necromunda Escher Juve. You don't see many female Servitors so I thought it was time that was rectified. The shotgun was fairly easy to clip away. It was replaced with various Hell-gun parts. The head is simply a servo-skull with a few additional shapes etc.
