I had already went through all these variants at home and the one that surprised me is below. In the original position and even in your variants there aren't enough men in the zone to pose a real attacking threat. It's best to get off that piece of shit 22pt anchor and leave your back men spread in order to remake a better anchor, or, worse comes to worse, the same one.
