Suitable Companion NPC Skills (Vanilla/Modded)

[Pokestar]

Hello, I've got a question regarding certain skills in the Creation Kit and whether these could be given to a companion NPC I'm working on both from a modded (i.e. Wildcat - Combat of Skyrim) and even more importantly "vanilla" game perspective.

The skills I'm not certain whether to give to this NPC are:

• DestructionNovice00, DestructionApprentice25, DestructionAdept50
• ConjurationNovice00, ConjurationApprentice25, ConjurationAdept50
• RestorationNovice00, RestorationApprentice25
• AlterationNovice00

Considering in the vanilla game spells for NPCs to cast cost half of the magicka, as for the player as far as I know anyway, I wonder whether giving the companion these skills was unbalanced/overpowered/got things out of hand. Then again, "Wildcat" for example, changes that so NPCs have the player's magicka and stamina costs for all actions. 

So I wonder: What is most in line with a vanilla (or still works well with) and modded game for balance in your opinion? Would you give any NPCs these cost-reducing perks or do you consinder them rather intended for the player?

Thanks in advance for any advice!

I figured it out myself anyway, giving the NPC said perks seems to work out fine for me.
