Yeah, that coupling system looks very similar to your prototype, G_E_C.
As for magnets, I just tested a rare earth magnet which easily picked up a 22 ounce mini-anvil. The magnet is 1" long and 3/16" in diameter. The same magnet will raise a steel bar 1"x1.5"x8" from a lying-flat position to standing-on-end, but won't quite lift it. Weight of the bar is 51 ounces. They'd work great as couplers, but you're on your own for uncoupling.
I think the ones shown by Schraddel are what you want.
