Hello Kevin,

I think this could be done in Audacity, by mixing the waveforms to a
final track, and viewing it. However, I think this would be somewhat
clumsy. I also think that I could do this in GNU Radio, with mixing
nodes and oscilloscope displays.

I have no experience with GNU Radio, but what you want could be patched together in PureData [1], Csound [2] (both showing the waveform in real-time as it is played) or GNU Octave [3]. PureData and Csound might have a steep learning-curve, if you have never used them before, but are both quite versatile DSP "patching" languages.

Another thought: Perhaps insert a standalone waveform visualization plugin into the sound output chain, just before the final output of the sound? Like Sonic Visualizer [4] or Glava [5]?
