Unwise. Ethylene-glycol itself is corrosive and acidic. Corrosion 
inhibitors are added to the coolant (silicates, phosphates, borates in traditional 
green antifreeze, organic salts in the Dex-Cool stuff) to keep it from eating your 
engine inside-out. intentially pouring coolant into hard-to-reach places on 
the engine is bound to cause damage anywhere it can sit somewhere and fester.

filling the pockets with silicone may be a bad idea too. if the fins really 
are heatsinks, changing the cooling ability of the engine is also asking for 
trouble. you could develop hot spots in the cylinders, etc. if you just want 
to keep them clean, how about finding some way to put some stainless steel 
mesh over the pockets to keep leaves from falling in? then you could just hose 
it out.
