A topic of "50h Quick-Host" with 80 hour turns is somewhat misleading.
You might consider 48 hour, no quick hosting. (48 is better than 50 (or 80) because the turns are due the same time of day and don't shift around.)
Or 48 hour QH, and make sure you get your turn in on the Last hour or so, thus kicking off the next turn, which you take, and probably have at least 72 hours, possibly 96, before the next turn is due.
This would work especially well if you ask someone in the game to delay their turn on those weekends, helping to ensure that it takes closer to 48 hours rather than 24 or less.
If you get one going, I for one would join (especially if it winds up having any sane hourly setting - 48, 72, or 96). But you still need a hosting solution, and if it takes a month to start, I may already have a full plate.
