I don't know if anyone is still reading this thread but from the way I understand it, in roll the 2 ELACs does not control different hydraulic systems like it does in pitch.
If you lose ELAC 1 and G then you'll still have both ailerons as ELAC 2 will take over with Blue system making the aileron dance.
The ailerons will only go into damping mode if you lose both ELACs or both G + B HYD. ref dsc 27-10-20
