Bullshit. They were planning to win, not die trying in vain. People may say they are ready to die for the mission but only brainwashed nogoods actually do it willingly, real men would only do it when there's no other choice. Shoot was perhaps already accepting his death, but as Knuckle demonstrated, they didn't go in planning to die. Gon would have never done it anyway; not in his personality or way of thinking. In the first place, his second goal is to save Kite, which would hardly go together with getting killed in seconds.
Not to mention what you said isn't replying to my point. Why delay somebody for an hour if the other alternative is to delay them for an eternity? Makes zero sense unless there's some heavier reason to choose the single hour.
