Opening the 2nd Origin gives the user a tremendous boost in Magic power, Natsu and the others that had their second origin released was already using it since they were behind the others at the point that they didn't train for three months, i doubt Lucy can gain enough magic power to open 2 gates in just 2 days of training.
