Adding Custom armor to a follower in the creation kit?

[CasparDark]

So i started making my follower, it's my first mod. I made the bare bones version and i thought it was time for custom improvements of the character. I wanted to add a piece of headgear from another mod. I loaded the data and equipped it, it worked fine. But now i have to load the mod with the headgear and my own mod both when working in CK and when playing the game. I wanted to know if i could potentially add the armor from the mod to my character, without keeping the full mod, and if this is a complicated process.
