Click-bait Title, Now click.

So I just recently decided to actually look at the server locations only to find out that I've been playing league on a server that actually isn't for my area (Jamaica). So I think I'm going to start playing a bit on there as my ping on the current server is average 150ms up from the oh so good 79ms I used to get. (I got used to it but I can get better on better ping.) So I want to know if I log into my main account and just change the region will I be able to us it as a LAN account with the account reset. And if so can I still go back to NA and my main account content will be restored. Or is it better to just make a new account all together?

P.S. Sorry for the click-bait and the lack of click-bait worthy content.
