Agree with PP's that it is kind of crazy to think that will work.
If this ADR is important to you, I would first try to move to later that evening, or to another day during your trip. If those options don't work, Go ahead and leave that ADR in place (keep checking though even on the day of whilst you are traveling to WDW) and if you get to a point in your travels that it becomes glaringly apparent that you aren't going to make it, go ahead and move it to another random day, then cancel it at that point. Doing this will make sure you avoid paying the no-show fee.
