I needed a dremel only to shave down Rose Tico's hood, the cylinder-looking things on her belt, and the little clip on the inside of DJ's holster in the back. Everything else was a straight swap.

I placed DJ's holster over Rose's belt, as DJ's holster only would have been too loose. I thought of using Rose's arms, but after trying Kuill's, I thought it looked like a better fit. He also has gloves so that made it easier. I did get some ankle coverings, but they were too long. They would have hindered the leg articulation. Not quite accurate, but I'm happy with how this turned out.

Head: Nien Nunb from Scoundrals Stock
