Elec-PS sounds Interesting. Since i gave up on Hydro-Boost (U-pull-it, stored it, got rid of it), there is fear that the Elec-PS may sit around for tossing. I suppose the tri-fecta would include an electric waterpump.
GM PMD 12S Alt +PS are a solution set, not a problem set. Particularly with redundant water pump cooling belts.
