Region question

Hi, I want start with design on my region, but I must know couple things before:
1. Can my region look like this (x=town, o=wild)
oxo
xxx
oxo
2. Can area like that be edited in 1 or I need 2 worldcut applications.
3. Is there limit how much comayors I can have in region.


Please answer fast because my current cost is 740K for towns, 540K for towns, 100K for portals, 40K for world edit and 60K for materials. I also found area.

 

thanks, I have one more question: can I make 5 towns (TOWNS, not REGION) and put that in that order? I need 600 long town.

 

ok, thanks
