Any suggestions for DLG wing connector, where you only need four pins and the light weight is important?

I got an idea. Get a pair of sub-D connectors with solder cups, like those here:

Cut away the metal shield and cut seven-pin blocks from the connectors. Four pins will be used for ground, power and two servo signals. One pin will be the key pin to avoid reversing the plug. Two pins at the ends of the blocks will be removed and replaced with short steel rods that are glued to the female connector - those rods will carry the mechanical loads. Female connector will be glued into the wing. Steel rods must be thick enough to keep the connector firmly in place.
