If they didn't time travel and just left the past the way it is, Shibano Sama probably would have been the foot clan founder instead of Hamato Koji.

Apparently Shibano Sama was referenced in The Legend of Koji and was the one from whom Koji took over leadership of the clan, naming it the Foot. Also, the "Kashima sword," likely belonged to the brothers whose holograms were used in the "My Brother, The Bad Guy" from season 5.

I got those answers from this thread:
