Your receiver likely has an option to assign a second pair of outputs as fronts. You would then have two left channel outputs and two right channel outputs. It might even have an option to change all 6 outputs to fronts so you have 3 left and 3 right. I believe this is called "all channel stereo" mode on my Denon.

There will be no efficiency gain but it will allow you to connect all four speakers in a much safer manner.
