You don't need 'harmonically unrelated' tones if you
are using sine waves (which have no harmonics). The
limiting factor would be how steep you can make the
bandpass filters... and how stable the recording
method is (wow, flutter, speed changes ?)

The lower audio tones will STILL be much slower to
recover.  I'd think that twenty tones would be really
pushing the limits of what you could do with practical
bandpass filters...
