Lancelot came back as a shade as he was in the start of season 4, so morgause would too, meaning she'd (even though she's already dead and would just be a shade) still be crippled from merlin's attack at the end of season 3. i don't morgana could go through morgause dying again, she couldn't cope the first time...
