Thanks man. I was finally able to do it. I managed to create recipes for all in-game armors.
The game's mechanics is set such as, if your crafting level is 5, then you permanently lose your ability to craft certain design of armors.
eg- if your crafting is 1, then you can only craft "ARM_CraftedClothTorso_01" variant. If your crafting level is 2, then you can only craft ARM_CraftedClothTorso_02 variant.
What I did was, changed all of their crafting requirement level to 5, and then made sure that any variant of ARM_CraftedClothTorso_XX can be crafted(it will be random). Similarly, found the recipe names of different metal, scale/chain, plate armors and made recipes for them. So now it looks something like this :
