Since Evony still has loads of bugs with age2, and the problems with Hcs and HHs I doubt we will see merges anytime soon.
HHs could be renamed similar to alliances so you have Beowulf-NA1 and Beowulf-NA2. But the issue would be messy indeed as the HHs in the Inn are already confusing and buggy even now.
The HCs are a nightmare. I like the option to choose HCs again with a special script, although that means you lose ALL your hard work building it up, which can be EXTREMELY annoying if you have a lot of HCs and have to rebuild the lot from scratch.
Also it would mean who ever logs in first can pick the choice spots. This can unbalance a game very quickly.
Imagine a powerful alliance with a large quantity of HCs all owning every HC near Atlantis, all 16s and all 14s. Overall the new server would have a VERY short life as it would make fighting that alliance almost impossible as they could take the core HCs on the new server within a few weeks.
The best way would be to consider a new type of city, and convert the 12s to this new type of city that can be ported once. The same rule can be applied to the bigger HCs already captured, they reduce the drafting distance (Atlantis cannot draft the ENTIRE server, and 16s cannot draft the ENTIRE state) so that the new 16s have some meaning.
The names of the city get renamed to match the server they came from. The NEW 12s would be named for the merged server.
it would mean you could have clusters of HCs.
Evony is unlikely to make the map bigger, although it would help with the drafting issues of HCs. They only did this once over the life of evony I think.
