Honest question , would it have changed much ?

I suspect so. The case was made in 102 minutes, a NY Times book detailing how 18 people on or above the South Tower's impact zone managed to escape in one of the partially collapsed staircases. Were the stairs built to firecode specs in place in 1966, and not in the flimsy manner expedited by Rockefeller, these stairs would have easily survived intact long enough for many more than 18 to survive.

I guess we're talking about not just brick, but reinforced concrete infused brick ? Anyway I'd be interested to read more about it, thanks.

Right, it's fireproof brick, isolated steel stairs, pressurized air, 120 m fireproof doors.
