SPERG, PM, ACE, and all the other major overhauls deal with it, often in rather different ways. There's also a lot of magic-specific overhauls. If you're looking for a spell package, there's only one real option: Apocalypse - Magic of Skyrim. It's hands-down the best spell package mod for the game in terms of balance, lore-friendliness, quantity, and quality. Among other things it adds a ton of utility spells and makes playthroughs centering on non-Destruction magic possible. The Master-level spells it adds require quests to unlock. Here is a highlight:
-Octato's Recital: GET THIS. What it does is cast a ritual. For the duration, you can cast up to three buffs, things like Oakflesh, the cloak spells, &c. After the Recital ends, it goes into effect until the next time you cast it with a new set of buffs. But what does it
do?
Every time you enter combat, those 1-3 buffs you entered into the Recital are automatically cast without cost. That's right, you'll actually
use the buff spells, especially if the overhaul you picked gives them a reasonable duration.
I could tell you more, but it's easier to just read through the
readme. Fantastic mod, fully compatible with pretty much every overhaul, and it adds a shitload of spells which give you new options rather than pretty effects.
