I'm wanting to kitbash the weapon(s) of Armada Rhinox who I'm using as a Classics/Universe character named Xenox. A friend and fellow board member is gonna give me a spare TM Rhinox horn if he ever finds it. I'm wanting to mod both horns to make them look like guns. Currently his main horn looks like this: I'm wanting to make it resemble the horn he has here: Doesn't look like it should be too hard, the front of the horn just needs to be hollowed out. How would one go about doing this? Another thing I was wondering about was how hard would it be to make Rhinox able to have 2 horns side by side in his beast mode. I was planning on both horns storing in his shoulders when not in use as it looks kind of cool as well as accessible during combat. I was also wondering how hard it'd be to give his horns energon blades sort of like Asuma's wind chakra infused trench knives: The last thing concerning me is both his horns will be different colors, I had planned to use tamiya light gunmetal gray spray paint on both of them and then detail them with a sharpie. How hard will it be to paint these? Will i need to prime them first? What color sharpie should I do the detailing in? Thanks for reading.
