>I'm considering downloading the expanded Cleric domains mod just to open up some more possibilities (and maybe lean even harder into being a Selunite with the Twilight domain).
You're already answering your question, but there are ways to differentiate two Clerics even beyond picking a different domain. For a duo, you might assign the role of healer/protector to one (this fits the Selûnite better) and striker/frontliner to the other. The first one can be either Life or Light domain and support their allies with Bless, Warding Flare, Warding Bond, and spells like Guardian of Faith that can soak up damage. This doesn't require any special gear, although the adamantine splint and healing-based items obviously pair well with Life. The other (Shadowheart) can be of any domain and just equip the Luminous set (https://bg3.wiki/wiki/Luminous_set) to focus on damage with Spirit Guardians, damage spells, and even melee strikes.
