I remember that a Privaron Espada, the one who fought with Ishida, said that an Arrancar couldn't go back to his form after Resurrection, but i might be wrong. Besides, MAYBE, if I'm right with what Segunda Etapa means, Ulquiorra was the only Arrancar able to archieve SE because he was the strongest of the non-Vasto Lorde Arrancars at the moment, and he could still evolve. But I may be wrong, Ulquiorra might have been a Vasto Lorde and even there could be higher steps in Menos Grande evolution unknown by the Shinigami.
