Brilliant Rusty - except that if you loose the belts you wont have much juice left for the EWP. 
 
The life expectancy (engine and pilot) is far longer without an alternator, than without water flow :-) 
 
Seriously, I think the advantage of the EWP might be removal of the mechanical pump load and weight. If I were going with EWP I'd get two and loose the mechanical pump. Go with a standard rad - it'll save you about the cost of the second EWP, plus less load on the belts to keep you're alternator running. 
 
I already have two EWP's, and running both, with no mechanical pump is still an option.   Unfortunately, packaging is still an issue.  Remember, skinny metal, not fat plastic :-) 
 
Rusty (I hope I get the chance to critique your work <g>)
