Try using a VPN and a Google Play store e-mail address set to the region you want to download an app from (I created one specially for this purpose).
I successfully set up a free one day trial VPN using an Android app. Then I fired up the Google Play store and installed the apps that I wanted. Then uninstalled the VPN app (which disabled the VPN). Now I've got the apps that I wanted and am able to use them in my region.
Aside: The content these apps serve up (Dutch video) is available in my region through the web browser. And, when there are restrictions the apps and the web browser respect the geographic restrictions so I really don't get why these @$!$)&^ apps are region restricted.
