As others have mentioned, this wouldn't be possible for all. For JP datacentres, you could potentially merge the datacentres from 3 into 1. And have them work together. Same for NA and its 2 datacentres, but EU would be the odd one out. I can't merge or cross-datacentre with any of the other datacentres, as there are no others in Europe. Plus then there's the spaghetti code others have mentioned (given all the technical limitations you hear, it's probably a safe bet to say even code in Malbolge is easier to understand). All in all, I don't think it is technically feasible to do this. Maybe if EU got a second datacentre, one could revisit this idea. But until then, I'm going to have to say no. Plus, they just keep adding to EU realms (as we seem to be filling up fast), rather than simply adding a new datacentre, so I doubt we'll see EU ever get another datacentre.
