SSE how to create new schools of magic?

[TuralyonProductions]

So I'm considering making a mod that will overhaul the Enchanting tree and skill by renaming it to Mysticism, adding/re-purposing some spells to include under it's school and change it's perks to also include bonuses to said spells. the problem is that I'm not entirely sure it's possible; while I won't be adding any new skills or actor values, i'm not sure if it's possible to edit an existing and already in use one as well as to make it a "magic skill" for the purpose of schools of magic. I believe Skywind has re-added mysticism somehow so can anyone tell me if this type of mod is even possible to create and if so how I could go about creating it?

The Schools of Magic are actor values and unfortunately new actor values can't be added in the Creation Kit. I don't know of a way to do this in a hack-ish way.

actually, I've recently spoken with a dev over at Skywind and they confirmed that they were able to readd Mysticism into the game by repurposing the Enchanting skill for it. They did this by removing the XP gain from enchanting items, and for every spell they want to change to mysticism, reduced its xp gain to 0 and created a papyrus script to add xp to "enchanting" on cast instead. the problem is that I'm not aware of what function is used in papyrus to add XP to a particular skill. Do you know how I can go about creating such a script and what functions/events I should use for it?

AdvanceSkill() gives xp to a particular skill by whatever amount you choose.
