Attach bone to bone?

I have character skeletal mesh and a armor skeletal mesh which contains shoulder pads and a helmet where each element is on a bone. Now I would like to attach the bone of the helmet to the head bone of character. I could not find anything in blueprint for that, is it possible at all?

It is for a strategy game were lots of units are on screen at once and they have interchangeable gear (armor and weapon). I would rather not separate the armor in separate components to keep performance good.

Have you looked into sockets? Similar to how they allow a weapon to be held in a socket that’s patented to the hand, just to shoulder or whatever body part you wish to add meshes to.
