Javik: Destroy
Garrus: Control. Mostly because he mega-approves whenever Shepard makes peace, and says she'll be making peace with the Reapers as a joke. Also, the whole archangel thing. Though I can see him being a destroy man, too.
Tali: Synthesis or destroy, probably depending on the Shepchoices.
Liara: Control. Come on, y'all saw the Shadow Broker DLC. That's the easiest of the lot.
Vega: Seems like a destroy man to me.
EDI: Synthesis. Maybe control if you renegaded the blazes out of her.
Kaidan: I actually think he'd go synthesis. If nothing else, because it seems like he has a real self-sacrificing streak. Maybe destroy if romanced because he's a sap.

Ash: Boom, boom, Reapers go bye bye.
...Actually, you know what? I bet this'd go like ME1, where everyone had their opinions, and you can even get Liara to advocate ditching the council if you bring the right person. I think it'd be two choices.
