That is not a valid test and you know it. DSLRs are nearly blind at 672nm and that is nothing to do with QE and everything to do with built in shaping filter. A valid test would be using Sony equipped CCD and then use SII filter. May I suggest a FLI Microline MLx285 for example.
The results will not be sad at all, I'm willing to bet.
