Requiescat turning into Confiteor, on the other hand, has some issues. Namely, if you are mashing Requiescat late into your GCD (like during a double weave), then you may end up queuing Confiteor, immediately ending Requiescat.
Just give it a shared internal cooldown of 1.5 seconds or so, or prevent the latter from being queued until the skill transforms (i.e. queue the ability, not the hotbar space) and delay the transformation until the first's animation is nearly done (such that it can still be chained for an instant use of Confiteor, but only if one goes out of their way to make that happen).

I'd just add that if you're going to combine RA into Atonement, it might be worthwhile to (1) make Atonement not break the main combo, and/or (2) make combos unbreakable while Sword Oath stacks remain.
