Guild Wars 2

I was wondering if it were possible to create a system where if one world held significantly more territory then the other two combined would it be possible to create a system where the two weaker worlds ally temporarily and cease hostilities. Such as allow players in the two weaker worlds hold a vote on a temporary alliance for a certain amount of hours/ days. If the two weaker worlds gain significant territory then the alliance would end early to avoid a situation where the alliance becomes overpowered. I know that such a system would be unlikely but it could make things more interesting.

For wvw I think that type of thing wouldn’t work so well. On the otherhand I would love to see it if they implemented guild battles with multiple guilds fighting each other on a large map and the ability to make alliances.
