So what is the problem again? Is the true problem is that you don't want to play slow players? Or is the problem still that you don't want to play fast games because you might time out because of unforseen events?
We don't want to play slow players, so we play low time limit games, but we dont want to play one, two or three day limits too often, because of unforeseen problems.
The solution is for two 'fast' players to play each other, but use a longer time limit game. I play many people who I know polay often. I don't mind playing them a 7 day game, as often we will finish several games in one sitting anyway. But if it was someone I am not familiar with, a 7 day game could drag out for months.
