SB intake mod: Fully seperate water passage from intake runners...

Anyone ever seperated the water coolant passage from the rest of the intake manifold to run a cooler mixture?
Something like the Air Gap intake, but then fully seperate.

I don't like the 'coolant' heating up the front cylinder intake passages, or the aluminium it's part of.
Something like cutting off the water-passage part and refabbing that seperatly with tubing and a thermostat housing.
