Given that all the servers are likely being kept in the same location for NA and then with a similar setup for EU I don't see why this couldn't be possible. Someone brought up the potential tech limitations on reddit but they didn't word it as if it was entirely impossible. Please if anyone actually knows how server administration works, I'd love to know the ins and outs as to why this might be viable and the potential challenges of getting it to work. Because if there's even a minor possibility of it working, it'd be worth it.
