Definitely strong challenge to apply cross server match making in GBG, no doubt on it. But it is not a impossible one. Even if it takes more than 3 weeks to implement it, no issues on waiting for it. IMO, it won't be a trouble to make the change within 3 weeks.Cross-server would indeed solve a lot of problems. When they released GBG they said they wanted it to be cross-server but the technical hurdles turned out to be too great (there's a lot more information flowing in GBG, and it's more important to be accurate in realtime - GE just grabs a snapshot of the data when you click on the ranking - data that consists merely of 8 percentages and some guild descriptors)
