not sure about 1, but it already orients itself using reaction wheels, which are basically what you are describing with 2. The issue is that its position at the lagrange point L2 is an unstable equilibrium, which requires occasional adjustment using thrusters. In terms of gravitational potential energy, its position in space is a saddle point, not a local minimum.
