Since you are working on one map (i think?) .. you should try an exchange with someone from eu
You host one of her's/his on na, she/he hosts host one of yours on eu type of deal ;)
(there are already threads dedicated to that sort of mapmakers exchanges/fraternizing)
I see many maps say that they're available on EU, NA, and other Battle.net servers.
How do the makers distribute the maps to different regions?
Note: My account is in NA
You buy a second sc2 or you ask a friend who is in said region to upload your map for you.
