This is the standard setup if you want to save channels (respectively output pins on your receiver). You don't need special servos for that. You just take two standard servos connected via a y-cable. Then you get the desired effect of one servo pushing and one servo shoving, because usually the servo arms are mounted 180° to each other:
Aileron Servo 1
| <- servo arm 1
----centerline of the airplane-----
| <- servo arm 2
Aileron Servo 2
