1. You are trying to make a damage spec based on SMITE. Smite spamming nonstop with holy fire use every time it's off CD does approximately 3-4 times less damage then shadow at the moment (depending on encounter).
2. Spell damage coefficients are highly unlikely to change. This because disc priests already do far too much damage with holy fire + smite, something that everyone in PvP knows very well. Buffing smite damage coefficient compared to other skills would be a horrifying mistake for PvP balance, making priests essentially in a class of their own as healers. It will not happen.
3. As we can safely assume that 2. will ensure that smite coefficient will not be beneficially modified, we can assume that it will remain largely untouched. This means that equivalent shadow spec with similar buffs will still do somewhere between 3 and 4 times the damage depending on the encounter.
4.New talent buffs listed include 15% buff in disc tree (which will be taken in PvP), 20% from chakra, extra 2% from searing light buff (taken for PvP) and 15% crit buff from penitence (taken for PvP), as well as instant cast but incapable of crit from surge of light.
Last point damns your spec, and general idea of pure smite spec for damage in PvE. Even with all the new buffs, the damage increase is still well under 50% instead of 300%+ required for competitiveness, and one of the two talents you want to pick is of a VERY questionable value outside PvP, as surge of light makes smite incapable of critting, while reducing cast speed from 2 sec to 1.5 sec GCD. I CBA to do the math, but it doesn't require much crit before it becomes a DPS reduction talent, or at least it's damage addition value would get reduced to nearly nothing.
Essentially, you're trying to create the classic "bastard child" spec. It wouldn't be good at anything at all, being horribly inept at both DPS and healing in spite of being able to do both, and as such it will never become an acceptable raiding or PvP spec.
Conclusion: Smite talents are for PvP, and PvP only. That's where it shines, and is one of the premiere class-defining skills. Not in PvE. And PvP disc, the currently only viable PvP healer spec lives and dies by penance and PS, while any holy build would live and die by GS (should holy ever become viable in PvP), as it is the only proper survival cooldown the talent tree has.
