One thing you might try recommending is have the 2nd wizard be an orb wizard, which is very good for control. This benefits from a high wisdom. Said Orb wizard could then pick up the cleric multiclass, and mabye grab a few cleric multiclass powers. This would add a bit more healing to the party without loosing much on the wizards part.
I think things might be difficult, but the party should do ok. 2 wizards is a lot of AE. They might have trouble with tough solo monsters, so that would be a thing to keep your eyes on.
