1. This strangly get's asked often. Is it possible?
In regards to game play the answer is ALWAYS YES. It's number 2 you need to focus on.
2. You need more details. Do you need save this world? can players go back?
Either way just design the world by a 3x3 grid of large space. When player moves from 1 grid area to another create new world on the edge of new space.
There are 2 approaches you can do.
1. Move the player and recenter when changing grid areas.
2. the world moves around the player.
however I don't believe anyone really has done this in C2 so i don't think there will be any examples. But I could be wrong.
