But seriously: harmonic amplitudes, durations, and consonances with respect to f0 also affects perception, But how fast you switch between the two sounds (or f0's) might be a greater variable than any of these. This is why we don't notice the pitch variance on traditional instruments as such but miss it when we switch to (some) synthetic spounds.

I'm also surprised that no one has attempted it. For one thing, there are always "theories in the air" about what intonation scheme musicians actually use (Pythagorean vs. equal- tempered, etc.) However, one thing to keep in mind is that most musical instruments don't produce absolutely constant F0's. There is always some variation, even when there is no vibrato. This could have a big effect on DL's. Also, there is the problem of how F0 should be measured when it is time-varying.
