I'd vote for just starting it with 36h+quickhost. The turn timer resets when it quickhosts, so a 24h timer would be constantly moving up earlier in the day. A 36h timer should still force people to play a turn every day as it shouldn't be running the entire 36h. It will just offer little conveniences such as allowing people to choose what time of day they'd like to play that turn, that the 24h won't.

That said, I'm be all for trying to take advantage of the quickhost and get more then one turn in a day for the first few turns when there isn't much to do if other people are up for it.
