Some other member of the D clan would take up the mantle get the gomu gomu and topple the government anyways.
Could still be luffy thought since Dragon would be a revolutionary anyways, luffy maybe joins his father instead of being a pirate because of shanks.
Anyways PK Xebec couldn’t do anything to topple the wg, he needed the gomu gomu, and he needed to wait for the two kings. He was too early, as was roger.
