spectral tonemapping possible?

I am looking for a way to apply a tone curve to images in Photoshop using spectral data--output curves expressed in the spectral space between about 400nm and 700nm. Is that possible, if so how? Working in 16 or 32bit is an option, if that helps.

An example of how you might use this is to get the spectral curves of a particular lamp type and bias an image to them, simulating the use of that lamp to produce the picture. The spectral curve will pump up certain wavelengths (colors/saturations) while suppressing others.

When you look at RGB spaces and LAB, it's hard to see how you might accomplish a spectral re-mapping. Any suggestions?

Thanks in advance!
