Adapter for using 1972 fusebox in 1970 car?

Has anyone thought of building an adapter that will let you use a 72 model fuse box in a 70 / 71 model Z?

I haven't looked at a 72 fusebox for awhile, but I seem to remember that it is just a matter of lengthening the wires by about a foot.

Since the 1970 fusebox is NLA, it might be worth looking into.
