Most people would agree that zoro would ultimately replace sandai with another sword.
So far, the prime candidate is nidai, simply because of the brief interaction zoro has with the sword and that it is a direct upgrade from sandai.
However, let's assume if ZKK were to occur, I believe it will possibly pave the way for zoro to regain shusui.
Reasons for regaining shusui after ZKK.
1) Zoro would be considered as the second-coming of ryuma, and why bury ryuma's sword when the new ryuma is alive.
2) Shusui can be considered as Wano's gift and appreciation to zoro for freeing the country.
3) Ryuma actually gifted the sword to zoro after his defeat, based on his will. Hiyori and the people of wano were not aware of it, but will.
