The .1 channel is it's own channel, it is not the low pass output of the centre channel. The only reason it's called .1 is because the LFE channel isn't full bandwidth. As a trial, get a DVD movie that has the THX tests on it. From those tests it is clear that the .1 channel is completely separate from all the other channels.
