Nope. You get an error forcing you to hard shutdown by doing that. I planned on giving a screenshot, but I couldn't use the button combo to go back, so that probably didn't even work either.
EDIT: On another note. Your eShop region is tied to your actual account, so it obviously wouldn't have worked anyway. I was curious myself though. I set the language and region to JP.

This is why we need an Account Spoofer, make a Homebrew to switch accounts for different regions.
