Assigning factions to npcs through equipment

[9zAZO]

Here I am back with another cry of help for scripting.
I'm currently working on a small mod for myself, adapting to roleplay for one of my character, but due to unexplicable errors that give me an instant freeze on Oblivion startup, I cannot touch the mod itself, so I need to come up with a reverse solution.
Essentially, since I cannot touch the aformentioned mod because of these crashes, what I need to do is to have this npc be able to join the Necromancer Dungeon and Necromancter Faction factions through other means, and I was wondering if, through scripting, I can attach a working scrip that adds them to those factions to a robe that this npc wears through the use of another mod.
I know it sounds convoluted, but the question is essentially is ''Do ''Begin on equip'' scripts work when npcs wear a piece of equipment?''

Thanks in advance to whoever can help me

The correct writing is OnEquip.

 

Your idea looks feasible but I don't know the scripting enough to make it work.
