You can process Kodachrome at home as a color film, but not likely with
success, roll after roll. It requires extremely precise time and
temperature
control because it only works if the developer diffuses a very precise
distance into the emulsion, and no farther, before it is neutralized,
and
it
must do this three separate times. I suspect making a rocket would be a
lot
easier.

The original Kodachrome introduced in 1935 relyed on diffusion
control. The film had fat interlayers between the color layers to allow
for
some variation. Process control technicians routinely used a microtome to
cut crossections of the filme to view under a microscope. In 1938 Kodak
introduced the "selective re-exsposure" process. In this process, there
were
red and blue re-exposure lights to make these layers developable prior to
the separate cyan and yellow developers. The magenta developer (last one)
had a chemical fogging agent. The re-exposure lights would be the tough
parts of the process to do at home. It is not impossible, but it is well
beyond the capability of the typical home darkroom enthusiast. You would
also need to find a source for the raw chemicals and mix your own
solutions.

By the way, did you know Kodachrome was invented by two musicians?

Yep. Both were named Leopold. Here are more details:
