Mysticism and Dawnguard Arsenal - Sun Spell Patch

This one's a dead-simple ESPFE patch to achieve a little consistency when using both Mysticism and Dawnguard Arsenal. Both mods add their own set of new sun spells, but the set from Mysticism is more expansive and cohesive, with equivalents to each of those added by Dawnguard Arsenal and then some. Dawnguard Arsenal's other changes, like the new bladed weapons and its changes to the vampire-slaying bonuses and set effects, remain in place: only Sorine and Florentius' merchant stock is changed.

Dawnguard Arsenal's Sun Ray spell tome has been removed from Sorine's stock, but in a similar spirit she will now sell Mysticism's novice Sunbeam and apprentice Sunlight Touch tomes. Florentius' stock is simply the same as though only Mysticism were installed, which means he'll sell an assortment of Restoration spells, both traditional healing magics and Mysticism's suite of sun spells.

Notes for Spell Research Users

If using Spell Research alongside this mod and its requirements, as well as a patch to import Dawnguard Arsenal's spells, it will become possible to accidentally discover the Arsenal sun spells via research, despite their being otherwise removed from the game. If you're using a standalone patch for Spell Research and Dawnguard Arsenal, this can be prevented by simply removing that patch or declining to import.

However, if you're using the Spell Research Patch Compendium, I've provided a script replacer that prevents accidental discovery of the deprecated spells. You'll still be asked to import them, but they'll be undiscoverable if you do. If you add the Arsenal sun spells via the console, you'll still be able to study their archetypes and craft spell tomes as normal - though this isn't intended to be used, and is only included for completeness.
