You just have to insure whatever is on the bottom isn't pressed by the backing, which is why I mention a small block with just the hole for the connectors. With only six parts including the header, it would be pretty quick to assemble these boards. Give yourself a few bucks for the labor and make a little package that doesn't require any soldering to install in the DCS-RC.
From some of the stuff I've seen, a lot of people would love to be able to do something like this and not have to deal with soldering.
