I don't know if you watch Farming the Wild on Outdoor Channel, but the UK host Mike Robinson is a big fan of what he calls a "hanging gralloch". I've seen him use a stick for a gambrel and a utility line over a branch to get the pelvis to a comfortable working height; he also just a stick for a gambrel, cut a limb off a tree at about chest height, leaving a stub, and just lifted the doe by the gambrel to set it over the stub and gutted it that way. IIRC it put the hams at about chest height, which looked a lot less uncomfortable than working the carcass on the ground.
I also saw on one of the FB groups, someone using a couple 2-3 link sections of chain to improvise a block and tackle for hanging deer. IIRC he used dynaglide with this.
Since MN DNR says I can't butcher in the field, the stick-and-stub approach is probably more my speed.
