Chris, I agree that the sound quality is fine, but the noise floor is high. What frequency signal did you use? I could try some filtering. Unfortunately, the track has very little silence, so it's hard to get a good noiseprint for noise reduction.
One problem with the whole approach is that the connection to the camera is unbalanced stereo in a single cable. No matter what we do, there will be some bleed. In fact, I got lots of bleed even when sending the pilot tone directly into the camera with a short dual-mono to stereo combiner plug. The problem is that we need to crank the signal so high in order to defeat the AGC. I should try a low tone like 200Hz. It will have less crosstalk and might be more effective at reducing gain at lower levels.
Before long the Magic Lantern solution will make this moot. We'll be able to get stereo signals into the camera, will be able to manage the gain of the preamps, and won't have to worry about artifacts from the pilot tone.
