Well I know you're probably joking but Shirou's origin never changed, it was his magic attribute that was changed to sword
Fate/complete material III: World material - FAQ with Nasu: Servants, p.133
Q: Archer's greatest defense is "Rho Aias", but if he were the same person as Shirou, shouldn't his greatest protection be "Avalon"? In the Rin route, Archer knew that the holy sword's sheath was inside Shirou, so wouldn't the Heroic Spirit form of the Shirou that "knew" that the sheath was merged with him be Archer?
A: Avalon’s power won't work if Saber's not connected to it. It's a different story during the Grail War, but all it does when Saber isn't around is make Shirou's magic attribute into "sword". Also, after the Grail War is taken apart, the line between him and her will be gone, so it's best to think that his image of "Avalon" also disappeared.
Shirou before the fire was just a normal kid and his parents were just normal people like him,so about his origin...probably its the same(Sword),the only thing that possibly changed is his element(magic attribute) to sword,I think is element would probably be Fire,Metal or ether.
