It's not quite finished yet but here is my Elite Trooper Decurion conversion.
As you can see it is based on the trooper medic. I cut off the assault rifle, which took some work to get the stock away since it was up close to the arm. Then I added a machine pistol from a weapon pack. I had to file it down a bit so that it would fit.
The left arm was easy since he already held it in a nice position with his fist closed so I just drilled a hole trough the hand and pinned the Punisher sword.
The head took some work to get off (I used a plier, but a dremel would have helped I think). Then I went to work with a file smoothing it down. Then there was the problem of the tubes he had on his chest which with his helmet off would look strange. So I went to work and clipped and, filed and clipped and filed again (again a dremel would have been nice) to get them off. This kind of ruined his chest so I broke out some green stuff and made some armour. I tried to give it a muscled profile to go with the Arnold style head.
Since I was impatient and wanted the green stuff to cure faster I put it under a lamp to get some heat. This made the base melt so I'm gonna have to give him a new one.
The head is from a Hasslefree mini (Wolf), which comes with three different heads so I choose the Arnold style head for this conversion (didn't think the Orc or Dreadlock head would work for a member of the Brotherhood). This was the easy and fun part. I drilled and pinned it in place and then just added a tiny bit of green stuff to fill a small gap.
