I am familiar with what you are talking about although I have never read the book. Dr. Kageyama's research is fascinating and should be taken seriously by every angler wishing to increase their number of hookups. Alot of the results of his research have been published in STS.

Part of his research is determining how water, in its various stages of turbidity, reflects and refracts light, allowing certain wavelengths in and keeping others out. The filters he uses are designed to filter out specific wavelengths and from what I understand mimic natural conditions fairly accurately. I doubt that you could replicate his results without having filters designed specifically to mimic these conditions.

Sorry I don't have any answers to your questions, I just didn't want you to feel like you were shouting into the wind...
