As in "rebuilding the game from scratch". It's been discussed at length in the past, and that's the only solution. We already have a unique ID for each nation in addition to the nation name, so we don't really need a new one like a Discord handle ... but that Unique ID can't be parsed to the whole game without a full rebuild.
tl;dr: not gonna happen.
