if its not too hard, maybe place a cardboard sheet directly over (half, or less) of the radiator to help reduce the cooling surface? Monitor temps accordingly, of course. If this is not satisfactory, switch to the engine insulation idea. or use a mixture of both.
Radiator block would help the circulating fluid heat up faster(less open faced cooling surface).
Engine "blanket" would help retain the heat for X amount of time once shut down...
Small radiator(less surface area)=less cooling efficiency, Bigger(larger suface area)=more colling efficiency.
*Its always easier to Heat something, But not as easy as keeping your engine in safe operating temps if you are unable to correct possible issue(s) immediately to prevent damage. Wind chill factors may play a part in what you can get away with safely for warmup. And what YOU are comfortable with.
Test Test Test.
