I keep 2 game bags & a contractor bag in the bottom of my pack, use the gutless method & put one side in each game bag. Then I just use the contractor bag as a liner & place both game bags in the pack leaving the contractor bag open & the treehouse lid open as well. Just gotta get creative with strapping the stuff that was inside to the back of the pack. Usually I just have a jacket or vest in the open center section so it’s easy to strap on the outside the 3 inside compartments still function as normal ( for me one has a thermos/water bottle, another with camera gear & arm, the last one has first aid, kill kit, saw, pruners & tree strap)
