Since the second season is going to be 24 episodes long and there's no way they could do Alicization in the remaining episodes (since Alicization is twice as large as all the other arcs put together), there's no doubt that some side stories will have to be adaptated to fill in the remaining time slot. Phantom Bullet is two volumes long. Mother's Rosario is one volume long. Going by the current rate, one volume = around half a cour (7 or so episodes). So, that's probably how much you can expect from Mother's Rosario. Caliber will mostly likely also be adapted, but that story focuses on the group, rather than just Asuna.
