I have thought about BW points to convert to southwest. You are paying about 2.5 cents for 1.66 cents of airfare at southwest. But its points towards a companion pass, so if you are close than it can make sense. Its no Wyndham, Choice or even Hyatt, but its WN points. In the end I guess I have decided that I will get my companion pass anyways, so why waste money on this.
