Why not allow for armour customisation in linking armour so they work as a set. You can group together all the items you use in their slots and create an armour set.

Or mixing Glass armour with Amber for a 7up set
It'd be a good way to manage your armour for particular battles and even role play. Bridging both the simplicity of Fallouts armour system and the enchantment heavy customs of TES
