Then you would need to figure out the spray flow rate so you wouldn't be
spraying more water than the core heat could evaporate and therefore wasting
it.  You would also need to figure out an adequate spray pattern, build/buy
the nozzles, water pump, water container, etc.  But, certainly doable.
Tracy Crook at one time used one when he was being held on the ground for
extend periods and needed more cooling than airflow from prop was providing.

A quick solution might be those spayers that they sell to sunbathers to keep cool.  A pump sprays an extremely fine mist, that is really quite cold.

Would a 'mist-assist' cooling system work better with a long plenum and thick radiator?  My thinking is that the extra distance would give the water sufficient time to evaporate completely.
