Please look at US patent # 3,658, 525 which is the process patent for the current Kodachrome (with a few tweaks in the final release). This patent has been abandoned since Fuji and Konica no longer produce Kodachrome type films.

I also have a source for the red sensitizing dye which forms a "J" aggregate of high staying power on the cyan layer emulsion. In fact, I have 900 mg of it left from my own emulsion work.

I don't want you to skin any cats. It would be so inhumane.
