I am afraid that opening a valve on pressurized cooling system with engine running will have quite drastic consequences, similar to what happens when radiator cap safety valve opens as a result of engine overheating.

Yes indeed, but the valve can be opened very briefly, or a nozzle of some type may be attached to release pressure slowly.
I wonder if the pump can be completely eliminated, or are the engines now designed in such a manner that they will develop steam pockets with no liquid contact and will locally overheat.
The size of the pump can be reduced quite a bit in my opinion/guesstimation assuming the engine is driven in econo-mode.
Another thing that came to my mind that i am kind of implementing is not using the radiator at all. Currently it is blocked by cardboard. And when the heat rises a bit, i turn on the blower fan and pump the excess heat in to the cabin.
I suppose the radiator fan signal could be rerouted to the blower fan, this is assuming the outside temps are cooler.
