Bi-wiring your center channel with a reciever that doesn't support it probably will not do you any good. You will basically be doing to the same job as the brass or gold shorts connected to your binding posts. Bi-wiring just let's you send the lows to the lowpass filter and the highs to the high pass filter directly without having the crossover do the work. Some people say you can hear a difference though without the fancy hardware in your reciever. In my experience with designing and installing home theatres I have yet to hear it. Bi-wiring with a reciever that supports Bi-wiring does have an audible difference as well as Bi-amping. Mostly while listening to music or during the quieter more detailed scenes in movies. It all depends on your equipment. If you have real high end speakers let the crossover do the work. If there just middle of the road to low end speakers give a try.
