Way to increase playable map size?

[555555]

Is there a way to increase the map size past the maximum of 256X256? I am making an epic-sized RPG and I am afraid I may not have enough room to do all I can do.

Use WEU. That's going to be big! 0_0

well you can make units small and camera close
so it will look like big

Nothing is as boring as an empty 256*256 map. IMO it's better to create a good terrain (perhaps even go for something smaller than 256*256) that is original, good looking, and re-use your terrain for multiple quests. Don't make 10 places on the map with trees, just stick to 1 or 2 forests.
