I had this idea a while back too, though it was pre-3.1 meaning before Disc priests and Holy priests both got their concrete roles in a raid as Tank healer and Raid healer, respectively.
Nowadays, even for Holy priests, intellect beats spirit on a 1:1 ratio as proven by the EJs.
However, I would opt for a spec closer to this
for raid healing and using the standard 57/14/0 build as Disc for tank healing.
My Holy spec is actually quite similar to yours, the only differences being some points in the Holy tree being rearranged and the addition of Enlightenment from the Disc.
Personally, I think the 6% bonus to haste is very nice for Serendipited
(dunno if I used the right adjective version of the talent :P) PoHs. Plus you get the 6% bonus to Spirit, which after being nerfed still is quite important for a Holy priest due to 25% of it being added to our spellpower.
The Holy talents that cap the tree being taken out of this build, Guardian Spirit and Divine Providence, are not that important to a Holy priest imo. After all, Holy priests ARE raid healers, and should not be needing to pop GS on a DPS or healer. The latter one, however, does contribute a chunk to our overall throughput (CoH, PoM, PoM's CD) but there is usually more than 1 healing priest in a 25 man raid which means another player's PoM CD would be already proccing.
Ultimately, I believe that in this case, throughput is being sacrificed for regen, which in Ulduar, I have found to be important for short, intensive fights that require you to heal now, now, NOW!
Of course, this is just speculation on my part and I am by no means an expert, so feel free to tinker and comment on my thoughts.
PS: Lightwell would work alright if the dps/tank/healers/whatever else is getting hurt would click it. However, imo, we should all stick to our respective roles in order to benefit the entire raid the most. This means, dps should dps, tanks should tank and healers should heal. Making them heal that way, is just like a faster bandage imo.
PPS: Thanks to everyone who helped me out with my Disc spec in the other thread. I realize I do sound like I'm trying to poke holes in the status quo, but after a while in WoW, it does get boring playing the same spec and you begin to wonder if you could improve it.
