Actually, it is even easier. You can, just like I did, create one more profile right on the xbox, and during confirmation change your country from Unated States to United Kingdom. You will get 1 month trial Gold account, and when you sign in, you'll be on Live UK. You can switch between profiles as much as you want.
BTW, can you in Larian make the full game available for download from Live UK? It will great.
