That sounds like a good BoP.
Keep rerolling until u get high dps holy dmg. (Easier said than done tho. my reroll cost for my BoP is 1mil+ per try now -.-)
I can do T4 max (solo inefficiently) only, can't comment on T6 lol.
With regards to CDR, the efficient way to do it is max rolls on slots due to diminishing returns.
Example. 5 slots of 8 CDR will give u 34.1 % (sum 40%) but 6 slots of 7 CDR will give 35.2% (sum 42%) there is a 1% penalty, penalty grows as more slots are used.
I had a theorycraft for crafted crus gears (shit luck on crus. 150+ hours only 2 akkhan, don't think i will ever complete, but then again, no RoRG as well)
Chest - Born's Frozen Soul
Shoulder - Born's Privilege
Bracer - Aughild's Search
Helm - Aughild's Spike
Gloves - Cain's Scriviner
Boots - Cain's Travelers
Belt - Captain Crimson's Silk Girdle
Pants - Captain Crimson's Thrust
Bonus Exp - 70%
Regen - 2000
AR - 50
Life - 15%
DR Melee - 7%
DR Range - 7%
DR Elites - 15%
Elite Dmg - 15%
Attack Speed - 8%
CDR - 20%
RRC - 10%
MF - 50%
With Bonus x2 @ 10%, BoP 10%, Gloves, Shoulder, Shield, and 1 ring 8% and 12% gem, Paragon 10% you will get a 59% real CDR (55% if you lose 1 8% CDR slot) in total, have all the set bonuses, and yet still maintain a very respectable dps and toughness.
A real alternative to Akkhan as its firstly very hard to complete, and secondly hard to get good rolls on all slots.
Now if only RNG will give me that RoRG.

Disclaimer: Based on my limited understanding of mechanics as well. Correct me where I'm wrong.
Edit: Cain's 2pc can be replaced by Asheera's 2pc same slots for a lot more survivability at higher torment. Personally I'm aiming for efficient T4. T4 to T6 to do at the same level you need, survive double the dmg, deal triple the dps and only get double exp and gold. lol. So many things to achieve for seemingly not much additonal benefit.
