If the motor is not turning over ie prop not windmilling then alternate hot air is not going to make any difference. Surely in a single the first job is to enter the glide and look forward to the landing, suitable sites having been noted as you proceeded up to that point? Unless you routinely fly at 10000 ft, of course. Completing that nice emergency checklist underground could well ruin your day.
Anyway, aren't we talking about SIMPLE types? A Supercub can obviously be flown quite easily with all vitals committed to memory, but if a checklist makes you feel more confident, especially if you don't fly very often, then so be it.
However, if you needed a checklist to fly something like a J3 cub then I'm afraid you could quite properly be considered a Divvy
