Consolidation is a big requested feature. Well, we can do that today with bots. Instead of Reddit-reposting bots, lets use Lemmy-bots to repost and consolidate Lemmy communities together.

EDIT: The community will need to be moderator only, the bot should be a moderator. Posts/comments should be mapped to the original topic. I think the only feature needed from Lemmy-developers is some way to globally link to a topic? But we can kind of work around that issue by making a consolidation-bot / consolidation-community be server-specific?
