With a little work, you can convert just about any model kit into a flat. Simply cut the side walls to be about an inch long, and then mount the structure against a backdrop. This is a relatively simple kitbash that requires only a straight edge and a razor saw, maybe a mill fill file to clean up the cut edge.
