Since there doesn't seem to be a topic for discussion here, let's forget about the unknown maps, although random maps would be more logical. It's much more important to understand how much time the game takes for two players. I think this time should be multiplied by 1.5. And that's how we can estimate the actual time it would take to finish a game with four players. If you postpone it, the probability of meeting up with all four players again...
During registration, I think a very detailed description of time predictions is needed.
For example, I can't guarantee 100% that I'll be available on certain days of the week. But I'm sure that I could dedicate 2 days a week, from 8 PM to 9 PM Moscow time, to this tournament. And I don't understand... Is it really possible to participate in this tournament with these constraints? I still have doubts.
Maybe you can explain how you envision solving the time problem.
And regarding the maps - how many hours of gameplay do they offer (obviously, it varies, but in a standard setting), or are they all different in this regard?
