Protestants cannot make that claim. Protestantism is essentially a protest against the Catholic Church, and therefore supposes that Church as previously existing. If Peter had not consolidated and built up the Catholic Church there would be no Protestantism to oppose it. In any case, Protestantism was unheard of until over 1500 years after St. Peter’s death.
