Just a simple head swap of Aveline with Lady Elegant (Potion NPC in Lowtown), made it more bearable to have her in my party.

Simply add it to packages/core/override/patch.
Add Aveline Armor files to packages/core/override.

Changed Armor file so it should work after she becomes guard captain.

Sresla brought it to my attention that the armour mod was not compatible with a lot of other mods, so with his ideas/help, the new version should work fine with other apr_ mods(except other Aveline ones) now.

Thanks for the advice and troubleshooting Sresla.
