How did you manage that? Or are you on PC?
The armor, yes it's a mod who let you access the inventory on close friends (or people you cast charm on). You can just ask the adoring fan to wait.
On a console uou can reverse pickpocket perma bound armor and weapon on characters as they are weightless. Summon a set of armor and weapon or use the magic stones, the one at the east riverside north of Leyawind gives claymore and cuirass who is hard to summon.
Now you need to damage the items, summon a scamp and get it angry on you if no suitable enemies is nearby. Let it hit you until the cuirass take damage and kill it with the claymore.
Repair both items and you can drop them. Wait until the spell times out or dispel pick them up again.
Now get a full set of armor and pickpocket the adoring fan, place the set on him and he should equip it. Now he look more imposing. Ask him to wait outside your house.
Now this can be used in better ways, get a lot of armor and weapon, around 15 sets recommend that you use duping here, reverse pickpocket onto the defenders of Bruma, very useful if you do the fight at high level. Do not give them helmets as they would look like daedra.
For added survival chance enchant the swords with absorb health.
