It's a possibility but still, Mine and Leone were the ones to stop Akame from going to save Tatsumi during his "stay" at the palace. I highly doubt that Akame and Leone would even allow Mine to leave the hideout but the possibility of Mine going to the excution without the approval or knowing of Najenda and Akame is pretty high.
