Again, as with Cana, it is a finishing move and as Obra has proved, it can be cancelled. And I doubt she will get that kind of power-up about now. I mean, even with Yukino's help she did summon her share of 6 spirits at once(probably more since Yukino doesn't have second origin) and I think that has left her drained of energy and she will need the remainder to re-operate the eclipse gate.
