I took Jeff's Gran soldier kitbash and made it rgb compatible and replaced the standard BH gran with it. Enjoy ;)

You'd have to replace the model .glm aswell. I also just learned that Infinity Blade, maker of the Merc Kyle Model and brother to Hapslash passed away in 2011 :(
unrelated funfact:
I mashed that statue model together from Rosh Penin's head & torso and Palpys arms & legs. Thats why it looks a little weird but hey that was ~10 years ago.
