as much as i like this idea and being able to play against players from asia, europe, literally from all over the world, i dont think this will ever happen or be possible since different timezones. however if it ever comes down to it then i would suggest to do it with euro timer default. that way asia would play at night and US in the early afternoon.

EDIT:
ps@dnx: when you complain about others complaining about how unfair CW is then dont forget that its not about the individual players main hero. its about getting his/her (and maybe friends) the max tickets. players who usually throw CW dont really need the rewards for themselves that usually represent "a drop into a barrel" to them. for that reason i would like to emphasize how important it is to significantly raise the rewards for the winner to make it an actual goal to get the first place and not being happy with a top 4 spot. also they may like to consider to extend the crown penalties to the top 4 or top 8 players
