I'm not a modder I just like to give ideas on mods.
Seeming as there are transformations in the game whether you're a werewolf or a vampire lord I thought seeming as there are many forms of undead for all the Paladin classes to kill then there should be a mod that allows a paladin to transform into an angel which is what a statue of Meridia depicts.

I was thinking about the powers that an angel could wield. Considering that there is the dawn breaker for Meridia's champion then maybe dawn breaker can start off in the right hand while there could be a spell similar to sun's fire in the left hand? Perhaps have the large angelic wings fly similar to that of the vampire lord. I'm just spit balling ideas for modders to have fun with.
