I realize the OP said no to a fat bike, but it wasn't a totally firm no . . . I find that my Moonlander is brilliant at riding the rutted, frozen MUP that I frequent. The rut edges provide enough traction and the 5" tires roll over everything. I'm not going to say I enjoy that kind of surface, but a fat bike will get you through it.
