The Lang is so different that it might be hard to modify. You would have to connect the two deeps, make a back door and think of a totally different mechanism to slide the frames since the top bar is flat instead of curved. It would be great if we can figure out a design that can at least utilize the Lang frames. My friend Mark is looking into having a man in Michigan try to copy his AZ hive. We may have an answer in a few weeks if he can do it. There is also a lady in Georgia who is having her carpenter build some.
