Ahh, clever use of a less-common design and it's mini (I assume). If there is one scheme I could safely say wouldn't appear, it would be a DCMS MechWarrior using mercenary colors. As the DCMS officers assigned to those roles seem as much ISF assets as anything, I recall in one of the Jihad books a short piece detailing a Combine attempt to bring the Azami back to heel which was said to be from ISF units, painted red and gold. As it was a Jihad book, who knows if that was the actual ISF or not. Otherwise, think of the most generic Draconis Combine scheme you can and go with that. I personally would use a combo of red, white, and grey.
