Just curious, why do you want to go to an electric water pump? They’re more complex than a mechanical pump, hence have more failure mechanisms inherent. They increase the load on the alternator. To my knowledge the flow does not increase with RPM with them, so the flow either has to be maxed out all the time to meet high RPM full throttle conditions, which will draw a lot of current from the alternator continually, or compromised to some average value . Sorry, don’t mean to be a downer, just trying to fathom the advantage on a street machine that has to operate under a wide range of conditions.
