Main Question or Discussion Point

If electric waveforms such as square waves, sawtooth waves, and triangle waves are really no more than sine waves with added harmonics, one could run such a wave through a bandpass filter (or several) and isolate one of the harmonics as a sine wave?

Yes!!! You need good and sharp BPF though. Also, it's all relative, it's all about how low you want to suppress the unwanted harmonics.
