>>8979718Mmmm so I was about to assume you could, but then I decided to test this with my series 1 chief and series 2 jerome. Hand on the top is Jerome's and hand on the bottom is Chief's. As you can see, the peg on Jerome's hand is a bit thicker and a tiny bit shorter, while the peg on Chief's hand is a bit thinner and a tiny bit longer. Likewise, the hole in Chief's wrist is a bit smaller than the hole in Jerome's. I assume with some heat you would probably be able to open up the hole on your mk 7 to fit the gungnir hand, but then it may not be able to accept its original hands anymore on that wrist.
