Since W is an omni and X is a figure of eight, and both are facing
forwards, there is little that you can do in stereo.
You can try using an MS decode to stereo, but W + X gives a forward
facing cardioid, and W - X gives a rearward facing cardioid. If
these two signals are played as L/R stereo, you will get a good
stereo image of what is on the sides, the front sound will be on the
left hand side and teh rear sound on the right. The stereo will be
coherent, but probably not what you hoped for.
Sorry! Not very positive!
