I've been doing this for some time. I had an extra Soliloquy Sat-5 (one for the center and one for a proposed rear center). I scrapped the rear center idea and put the pair together in the front. With a big projection screen, it helped widen the soundstage some and alleviated the stress on the single speaker. I have a 6 channel Mac powering my system using a splitter on my center out.
The sound is great. Lots of extra headroom. I have the centers laying on their sides in a general MTTM configuration. It works way better than a single center.
