I saw the Ascetic archetype from Kobold Press, but as others pointed out, it basically gave up nothing to gain many bonuses. So I'm trying my hand at it.
I put a note at the top saying that this modifies or replaces all aspects of the Cleric class, so it's not compatible with any other archetype. I did that both because it's true, and because I'm not sure how I'd describe how each ability or feature replaced things like spell levels.
This Ascetic cleric can only cast spells up to 6th level with Diminished Spellcastin and no spontaneous casting of cure or inflict spells, does not have Aura or Channel Energy, has slightly different Class Skills, keeps its medium BAB, d8 hit die, and skill ranks per level, and it only has one Domain (or an option to have two inquisitions).
(Since inquisitions are so much weaker than domains, I don't think a 1to1 swap works. One domain for two inquisitions seems better to me, and it's a change I'd personally give to the inquisitor or any other domain class that wanted to take inquisitions over a domain.)
So yeah, what do you think?
