Divine Source + Conduit of Divine Will + Redemption subdomain = Instant Atonement?

[Bardess]

So there's a LG oracle who went Mythic and took Divine Source, the Redemption subdomain, and Conduit of Divine Will.
Divine Source says:

If you're a cleric or you venerate a deity, you may change your spell domains to those you grant others.

Does this mean that an oracle may replace her mystery spells with those of her selected domains?
Plus: does Conduit of Divine Will work with mystery spells too? Would it work with domain spells replacing mystery spells?
And so: would my oracle be able to cast Atonement as a standard action by combining those two mythic abilities?

I think the intent for that bit was for other classes that got domains. At the time of release that included religious Druids and (I'd have to double check) Inquisitor. Later expansion was limited to uh... Sacred Servant Paladin, but it still doesn't hurt to future proof.
