Seems like a lot of maze for very little cheese.

You can get 100 volt 160 amp rated pieces for, not real cheap.

Problem with Schottky diodes is they really don't like to be hot.
Between 50'C and 100'C they lose half their power carrying capacity.

These 160 amp diodes really are only good for 140 amps, if I can keep them at 50'C (as in they can not go in the hot engine compartment).

Typically alternators electronics are rated for up to 200'C.

Why stop at Schottkying the main rectifier, why not replace the half wave voltage rectifier for the regulator?
That should decrease the RPM at which the alternator comes up to the desired voltage and increase its output.
I like this mod for those reasons.
