Would like to see some specialty fire lays, such as a Dakota Fire hole, on top of snow/wet ground fires, etc.
Assuming at least a few inches of snow, would like to do an igloo with my igloo building tool, do a snow cave if there is enough snow or a suitable nearby snow bank, do an exercise showing how much snow needs to be melted to get 16 ounces of water.
Pulk/sled systems, how to pack them and how to use and control them.
Building tent/shelter windbreaks and fire pit windbreaks.
Methods of (successfully) getting a cord/rope into a tree for supporting antennas, bear boxes, and tents/tarps.
Amateur radio fox hunt. (Might not be the best time for this, though.)
Proper use of axes, hatchets, tomahawks, manual saws.
That is all I can think of off the top of my head.
Just my opinion.
