Sounds very interesting.  I've been wondering about a perceptually linear color
space, though none that I have seen looks linear to my own eyes--not Munsell,
not CIELAB.  (I am hearing of CIELUV for the first time, though.)

However, it strikes me as overkill for a ray tracer, so I agree with Clipka that
it should be low priority.
