Brown v. Board of Education, with out “all deliberate speed”

how would Brown v. Board be different of the language “all deliberate speed” hadn't been placed into the ruling by pro-segregation members of the court? in OTL it was used in the south to keep segregated schools till the late 1960s (Mississippi till 1968). what if Earl Warren had dumped his hopes for a Unanimous opinion and went for a stronger ruling?
 
It would be up to the President to enforce it. Eisenhower might.
It would mean the Dixiecrats would step up attacks on the Judiciary too.
