I would forget underground, too dark and possible water seeping in. Rabbits might like it.
I think ventilation will be the hardest to adapt. In traditional coops we use low and high vents for different weather. The nice thing is if its deep enough. It will stay pretty solid temps year round.
I don't think it would be that hard. Everything except Ventilation. But heck if moneys not a concern there are ways to vent areas like that.

I don't think you'll enjoy cleaning it out when the time comes. And it will come.
my coop is built into a bank, with some of the potential benefits and problems you have noted. so far it has worked out very well. it's kind of passive geo thermal. it stays cool in the summer time, is open to the north with spots where the sun hits in the morning and evening inside the coop. it has stayed remarkably dry but it is not in a hole, just a bank on one side. the main advantage for me has been the clawing back of otherwise unusable yard space be terracing. I did have to add a wall where the coop goes below the soil line.
