Hi, Julian,
I started playing with the sensory dissonance curves patch, and I modified it to plot the one octave dissonance graph for up to 6 frequencies. The important part of doing this, in particular, is to look at how the spectrum of the instrument influences the set of intervals in a tuning over which the instrument is most consonant. See William Sethares' Tuning Timbre Spectrum Scale for details....and maybe some revisions on my approach here.
