Rogue|Ranger.
Two daggers, chose powers that work at melee/thrown. If you have CA, use the Rogue powers, if not, Quarry and use Ranger powers. Use the Hybrid feat to chose Brutal as your class feature.
(Warlord/Ranger/Fighter)|(Warlord/Ranger/Fighter)
Find a fighting style feat that has a couple benefits you like for a couple at wills, and chose your classes based on that. Good synergy with some of these combinations.
Wizard|Artificer
The hybrid ability to use any implement from either class with any power helps out here. And notice, both classes have builds that are Int primary, and either wis or con secondary. Not sure what to pick up as the hybrid talent feat....
