I think it could be possible to host a tournament, maybe in a league format that gives the option to form 4 player teams but also allows more small teams to compete. Also the timing issue could be solved that way. In case some team members cant find time to participate only the other members of the team can play against each other, or play multiple matches. The only challenge here would be that if the strongest player of t2 gets to play many 1v1 that would lead to unfair outcomes as he plays the average of the other team. Although there could be the option that the other team would also be allowed to choose a player of their wishes to compete. Also their could be rules that force all team members to distribute games equally.. plenty of solutions possible... and of course it can get kinda complicated. I can work something out though in case there is intrest. Also it could encourage a more versatile choice of civs.
