Barring that they could have created a diversion, such that one of the ships could turn around and lightspeed through the ship. Have Poe make one of his crank calls again. That seemed to keep them preocuppied for a while, long enough for those extremely slow bombers to get close. Better yet, sacrifice another one of the smaller ships, by having it attack Snoke’s ship, turn around another one, and voila, almost everyone get’s to fight another day.
But they couldn’t have done that. They are literally on the outer edge of First Order weapons being effective against their shields. To turn around would have have taken them into that zone and would have been blasted out of the sky. Just look what happened to the medical frigate the second it ran out of fuel. All the info you need is within the film.
