I will admit to having abused medical equipment centrifuging and chromaticly filtering inks... but such tricks do not offer hard or fast info about any of the above. Gamut, color balance and reflectance are all related to some degree to how the ink is positioned on a given media as well as settings used, so only relative data could acheived this way, not anything absolute. Component colors could indeed be determined, but reflective prints, unlike some transmissive color sources (notably LEDs) are not point sources at a given wavelength, but whole big chunks of the spectrum, reflecting at the same time, in order to reflect enough light to look bright.
