Connecting Four Speakers In Unusual Serial/Parallel

I have bit of a dilemma. I am new to this stuff but think I can do anything - hence I am confused about what to do. I have a home theater with three platforms in stadium style. Originally was going to have one surround speaker for each platform on the left and one on right. So I would have had three speakers for left channel surround and three for right. But three speakers don't hook up well. So I added a fourth speaker to middle platform. Unfortunately, wires already sealed up in walls don't allow me to hook up four speakers in traditional serial/parallel setups to keep all four 8 ohm speakers at 8 ohms. I only have two wires going from the amplifier to speaker A and two to speaker B and two to speaker D. (Typical parallel hookup). Since speaker B and C are next to each other I can do anything I need to in that location. I could not find a wiring diagram to do what I want and don't know if it is possible since I am struggling with parallel/serial hookup to keep impedance correct. Can I connect speaker A and B in parallel and then connect speaker B to speaker C in serial which is connected parallel to D? If not is there any way to make the hook up without running a third wire from speaker A to B or C?

Wire speakers b & c in series and speakers a & d in series, then connect the two series pairs in parallel. Two x 8 ohms in series is 16 ohms. Two x 16 ohms in parallel is 8 ohms.
