There is a variant of this build that I've been thinking about that doesn't use a shield. Instead, it takes the Staff fighting feat to turn the staff into a double weapon with the defensive (+1 AC) and off-hand properties. You can then take Two-Weapon Fighting (+1 damage), Two Weapon Defense (+1 AC and +1 Reflex), multi-class into Sword Mage (Initiate of the Blade feat), and take Intelligent Blademaster.
It's more feats, but don't need to buy your strength as high, and a higher wisdom helps your Will defense, and Thunderwave At-Will. And you are getting +4 AC and +2 reflex from your staff, and (with a 22 Int) can make a basic melee attack with a +17 bonus, doing 1d8+10. Not too shabby.
