Insulate the lid or have a straw bale that rests on top. Build a cover over the whole thing so you don't need to dig it out every time you want something. Might make regulating temperature easier than your suggestion.
I soooo... totally want one to! It's just not making it onto the list.
I really, REALLY want a root cellar.
I do have a large 4 foot overhang on the west side of the house. I could, in theory, build a 4 foot by 4 foot box. Make it 8 feet tall, build in some shelves to separate it into 4 different sections. I could surround it with some hay bales, and figure out how to make an insulated door.
