No! Obviously no!
A leap hour? You want to let sunset/sunrise drift up to an hour off? You don't see any problems with that? That's one of the stupidest things I've heard smart people say in a long time.
If adjusting a leap second every couple years is just too damn difficult, then use a leap minute that you need to adjust every hundred years. I promise, it's a hassle you'll only have to deal with once in your lifetime.
Though I warm you, there may be unforseen issues with that as well, it might be best to just keep on doing things the way we have been.
