This is just an idea I had last night, what if the realms of the gods (UW, FoW and any future realms) were fought for in separate halls?
Rather than just the Hall of Heroes you could have the Hall of Grenth, the Hall of Dwayna etc with entry to each realm linked to whichever region is holding the relevant hall at the time.
This would mean that even if your region isn't holding the UW hall, there's still a chance you could have access to FoW if your region was holding that hall. This would obviously work better if they introduced more realms of the Gods (or maybe tie in the elite missions?) but at least favour wouldn't be an 'all or nothing' deal.
I know a lot of people want the tie between PvP and high end access severed but if ANet want access to remain linked, I think this could work.
Just thought i'd throw it out, what do you guys think?
