actually after harvest the bud is heavy and wet, curing in the bag is to draw moisture from the center of the bud after its been hang dryed on the outside, so to ''cure'' you bag it and check it, wet leaves would keep the moisture in the bag, not saying its not a good idea, but by the way youre asking its as if you cut them all off, if you left them on the plant then you would answer your own ? preserve them by not killing them, but since you did already and youre not worried about the trichomes on the leaves then i dont see why putting it in a wet paper towel in a seeled bag in the freezer wont work, just when you take it out, let it thaw before opening the bag, all the moisture should come back if its simply froze while it still has moisture.
