Container attachment

For the container attachment to the core building, I would like to be able hang it off of the frame as seen in the images below.... I really need Kurt's opinion on this, but my idea is that there is a frame within each of the containers that can be attached to the core frame at 6 points per container..... I could be way off in terms of the type of attachment, but I think that it can work in theory.... I just have to get the connection down..
