I'm also trying to build a dragonborn cleric with low wisdom, but not as low as this one 
Basically I want him to have 13 dexterity, to pick the feats Raging Storm, Astral Fire, Two Weapon fighting & defense, and armor specialization.
Although it's possible to choose only strength powers, most Paragon Path powers use wisdom.
So, I'd like him to be able to use some of his wisdom powers.
Question: generally, what are the changes of hitting with 12 wisdom vs. Will?
Because Will is usually the lowest for monsters.
