Very, very little chance it's possible. I'd say that getting 3x int on chest has a higher chance.
If a faction can't TW in the usual time, maybe they can message a GM and inform them of their preferred time range, and the other faction leader can do that also, if they reach a consensus maybe the GMs can adjust the war timezone ? If no consensus is reached the TW happens in default time ?
