Claws for Daemon Prince

So I have a bit of a crackpot idea that I have no idea if it’ll work.

I’m making my kitbashed up daemon prince based off Fog of Gore’s from the Mother of Nightmares kit from AoS. However, I wanna give him some different weapons. I already have bits for the infernal cannon arm, but I wanna give my prince a two-bladed claw gauntlet like the ones that the Primarch had.

So? Please help? Please? What bits or other materials could work for this?
