I'm with Beagle. Rudder isn't there to provide roll control. It's a *yaw* control - so use it for that.
After recovering from the stall - in whatever angle of bank that might be - and the aircraft is flying again, then use conventional coordinated aileron & rudder to roll to the nearest horizon. Once wings level, pitch to recover to S&L or climbing flight. If power is available then select full power once the angle of attack has been reduced during the stall recovery actions.
