The idea here is that you are a primary damage dealer but has the ability to immediately switch to healing when entering a particular damage heavy boss phase or some unfortunate nuke phase where healers suddenly drop dead, I call it the First-Aid spec.
The tools you have are:
PW: Barrier, No-cooldown PW: Shield, Circle of Healing, Power Infusion, Light Well, Chakra, and Archangel.
You need 3/3 in Divine Aegis because your smite will crit a lot when you deal damage. If 45% of your damage is converted to healing, that healing will similarly be critical hits, you will have tons of DA stacking on multiple targets when you deal damage, further enhancing your "healing on damage" utility.
Archangel from a smite perspective is very interesting. It's similar to a spirit tap button when you dps. You do not use it when you dps, only after everything's dead, then you "tap" it and get some mana back, as re-stacking the mana reduction buff is inefficient. It is also the first button you press when you go into first aid mode. You lose your dps buff, but gains a healing buff and some mana back, very useful.
I could just imagine this spec go insane in a raid situation. Oh shit moment? No worries, just drop PW: Barrier, activate power infusion, CoH + PoH spam, after PI finish, you use your no-cooldown PW: Shield and bubble everyone up. If there's AOE opportunity, you start spamming holy nova, not only does it do damage with 50% more crit, but it also heals AND proc divine aegis. O__O
