Unfortunately, frozen jals will lose their skins and become very soft when thawed. They'll cook - eventually - but you have to then overcome their mushiness by cooking longer. Doesn't work well with the bacon on there.
Go with Paul's suggestion: Assemble in advance then fridge them rather than freeze. They will be fine in the frisge for a couple or three days. The shorter the better but don't sweat it. If you need a three- or four-day advance then no big deal. Place them in a hard/firm Tupperware (or the like) container on a double layer of paper towel, ditto on top, with a sturdy lid. Use a few containers if necessary. If you can keep them from jostling around they'll be fine. Whatever ice you have in the cooler will be sufficient to keep them chilled enough. Safety-wise, cooking will handle pasteurization so no issue there.
