Here are some. Most of the combinations are IMO of little use
(sines with some hash or buzzer tones) but you can get some nice
reedy sounds by swapping adjacent high-order bits. Amplitude
changes give you unusual, evolving timbres reminiscent of wave
shapers.

I also tried swapping more than two bits but didn't come across
anything radically different.
